    Notes: Summary The orbits of 13 mammalian species (Pig, sika deer, domestic sheep, horse, cat, fox, racoon dog, marten, rat, rabbit, crab-eating macaque, japanese macaque and man) were stained with silver nitrate and dissected under a dissecting microscope with special attention to the presence and location of the accessory ciliary ganglion. Some preparations were stained with thionin and examined as whole-mounts in a transmission microscope. The accessory ciliary ganglion was present in all 13 species, although the number and degree of development varied greatly from species to species. The accessory ciliary ganglion could readily differentiated from the main ciliary ganglion in the following respects: it was located on the short ciliary nerve, and it had no root derived directly from the inferior trunk of the oculomotor nerve and it never attaches to this nerve. In many species, ganglion cells were also scattered in the short ciliary nerves in the stained whole preparations. In a few species, there were one or more small ganglia on the nerve to the inferior oblique muscle.

    Notes: Summary The biomass of newborn snails was higher in paddy soil without rice plants than in the soil with rice plants. There was an inverse correlation between shell width and concentratins of Zn and Cu in snail flesh. The Zn and Cu concentrations in snail flesh were extremely high compared with those in the paddy soil surrounding the snails, possibly because snails ingest sludge, one of the main components of the composts. These results suggest that this type of snail may be used to eliminate Zn and Cu from paddy soil when composted sewage sludge has been applied.

    Autonomous metabolic oscillation in continuous culture of Saccharomyces cerevisiae grown on ethanol (1996)

    Notes: Abstract When the yeast Saccharomyces cerevisiae was grown under aerobic continuous culture conditions with a medium containing ethanol as carbon source, an autonomous sustained metabolic oscillation appeared. This oscillation was observed in rates and concentrations of various parameters such as, ethanol, oxygen uptake rate, carbon dioxide evolution rate, NaOH addition rate for pH control, acetate, and intracellular pH. No changes were observed in concentrations of stock carbohydrates. Intracellular pH changes were out of phase with oxygen uptake rate, which was reverse of the results with glucose-based oscillation. These results suggested that changes in glycolytic flux and intracellular pH were not regulating the oscillation. Analysis suggested that one of the oscillatory regulation points was located in the ethanol assimilation pathway.

    Notes: Magnetically induced super-resolution performance for a center aperture detection scheme in a double layered magneto-optical storage is discussed. In order to make a readout layer thinner for better media lifetime, the effect of Ta and Pt additive elements in a readout layer GdFeCo on recording performance is systematically studied. Ta is found to be most effective in making it possible to reduce the readout layer thickness for an acceptable recording performance. For the mark length of 0.5 μm, the thickness can be reduced to 60 nm with Ta (1.9 at. %) from 80 nm without Ta for carrier-to-noise ratio (CNR)≥42 dB. © 1996 American Institute of Physics.

    Magnetic and magneto-optic properties of rapid thermally crystallized garnet films (invited) : 35th Annual conference on magnetism and magnetic materials (1991)

    Notes: A new technique to improve the morphology of sputter-deposited bismuth garnet films for optical storage is discussed. This technique employs high ramp-up rate annealing in a nitrogen atmosphere, which leads to a smaller grain size and smoother surface than a conventional oven annealing or in situ crystallization process during film growth. By utilizing this technique, the films can be successfully crystallized to the grain size of about 200–300 A(ring), and a high coercivity ((approximately-greater-than)kOe). Multilayer films of garnets with other additions such as Cr and SiOx are also discussed. These multilayer films can provide better morphology and high coercivity.

    Magnetic and magneto-optic properties of Bi-substituted garnet films crystallized by rapid thermal processing (1990)

    Notes: A new technique to crystallize as-deposited, amorphous phase in (BiDy)3(FeGa)5O12 films is presented. This technique employs heat pulse annealing and leads to improved surface smoothness and smaller grains, in comparison with conventional oven anneal and also with in situ crystallization during deposition. Rapid thermal annealing was accomplished in a heat pulse apparatus with a ramp-up rate up to 50 °C/s. Upon heating for several seconds at about 650 °C, a single phase of garnet is formed. The samples were polycrystalline, but exhibit a perpendicular magnetic anisotropy of 104 erg/cm3, and a high squareness of Faraday hysteresis loops. The coercivity is typically 1–4 kOe. A systematic study of the effect of a ramp rate on a microstructure and magnetic properties has been made. The result indicates that the ramp-up rate is a key to controlling grain size and surface morphology.

    Different mechanisms of spin reorientation in exchange coupled double rare earth-transition metal layers with in-plane and perpendicular magnetic anisotropy (2000)
    [S.l.] : American Institute of Physics (AIP)

    Notes: The objective of this article is to clarify the spin reorientation effects in exchange coupled layers based on rare earth and transition metals with in-plane and perpendicular anisotropy. These systems are proposed for high density magneto-optical recording with super resolution readout. Two mechanisms are found to be responsible for this change of the magnetization direction with the temperature. The first mechanism is an intrinsic spin reorientation in the GdFeCo layer and the second is the exchange coupling force between the perpendicularly magnetized TbFeCo film and the in-plane GdFeCo film. With appropriate adjustment of the compensation temperatures and the thicknesses of the films, it is possible that the one or the other mechanism dominates. The experimental results are in agreement with a numerical calculation of the magnetization profiles in the coupled system. © 2000 American Institute of Physics.

    Activation volume and magnetic interaction in longitudinal CoCrPtTa magnetic recording media (2000)

    Notes: The thermal activation volume (VA) is studied for CoCrPtTa longitudinal magnetic recording media. VA is found to strongly increase for smaller reversing fields. This trend is also continued in small positive applied fields. The activation area (SA) at the same reversing fields are found to be in reasonable agreement to each other for different media thicknesses. The thinner magnetic films show a larger SA near the coercivity, while δM remanence curves indicate that the intergranular exchange coupling becomes stronger for thinner media. Surprisingly comparable read/write performances are found for different media thicknesses. © 2000 American Institute of Physics.

    Micromagnetic study of readout process in magneto-optical multilayers (2000)

    Notes: The areal storage density of magneto-optical (MO) recording can be increased with the magnetically induced super-resolution (MSR) readout technique. In the present work, the effect of laser energy, disk velocity, and cooling time on the magnetic reversal processes in the MSR technique is discussed. The magnetization distribution and the temperature profile within MO multilayer media are investigated based on a micromagnetic model using a heat conduction theory. The magnetization of the readout layer, initially with in-plane magnetic anisotropy, can be switched perpendicularly to the film plane in a small temperature region. This magnetic reorientation depends on the strength of the exchange coupling between different layers. The correlation between this exchange coupling and dynamic parameters is discussed. © 2000 American Institute of Physics.

    Observation of thermomagnetically written domains by Lorentz electron microscopy in Tb-Co and Tb-Fe-Co disks (1988)
    [S.l.] : American Institute of Physics (AIP)

    Notes: For better understanding of the read/write properties of magneto-optical disks, thermomagnetically written domains were observed by Lorentz electron microscopy. The domains were written in the quadrilayered medium with 25-nm-thick Tb-Co film and in the trilayered medium with 50-nm-thick Tb-Fe-Co film, which were sputtered on pregrooved resinous substrates. Recording power and frequency were varied at intervals of 3.5 mm in a radial direction of the disk, and each recording position was observed individually. Qualitative understanding of the read/write properties, such as carrier-to-noise ratio (C/N) and jitter, were well achieved from Lorentz images of the domains. It is found that the C/N value of the Tb-Fe-Co film with a higher figure of merit (Rθk ) is lower than that of the Tb-Co film with a lower value of Rθk . The reason for this is believed to be due to a larger variation in domain shape in the Tb-Fe-Co film compared to the Tb-Co film. A careful observation based upon the image processing of domain bits reveals that the jitter is mainly caused by the irregularity of the domain shape near the edge in the Tb-Fe-Co film.
