    Easy-axis transition in epitaxial face-centered-cubic Ni80Fe20/Ni/Cu(100) (1999)

    Notes: We have studied the effects of ferromagnetic overlayers on the magnetic properties of step-wedged fcc (0–100 Å) Ni80Fe20/50 Å Ni/2000 ÅCu(001) structures. The perpendicular magnetic anisotropy (PMA) was found to be sensitively dependent on the NiFe thickness. An easy-axis transition from out-of-plane to in-plane was found to occur at a NiFe thickness of 36 Å with a corresponding domain structure observed by magnetic force microscopy. The absence of strain in the NiFe film as evidenced by reflection high energy electron diffraction suggests that the volume anisotropy of the NiFe films comes entirely from the shape anisotropy. The easy-axis transition in the fcc NiFe/Ni/Cu(100) system can be understood to result from an additional volume anisotropy which forces the Ni magnetization to lie in-plane. Our findings open a new path to controlling the critical thickness for PMA in this system via ferromagnetic overlayers. © 1999 American Institute of Physics.

    Crystallization and hard magnetic properties of Fe–Co–Nd–Dy–B amorphous alloys with glass transition (2000)

    Notes: Glass transition followed by a supercooled liquid region was observed in the composition range of 4–56 at. %Co, 2–4.5 %Nd, 0–1.25 %Dy, and 18–30 %B in melt-spun Fe–Co–Nd–Dy–B amorphous alloys. The largest value in the supercooled liquid region (ΔTx) was 45 K for Fe66.5Co9.5Nd3.5Dy0.5B20. The crystallized structure consists of 2:14:1, Fe3B, and α-(Fe, Co) phases and their grain sizes after annealing for 420 s at 933 K are 15, 15, and 50 nm, respectively. The interparticle spacing of the 2:14:1 phase is less than 50 nm. The remanence (Br), coercivity (iHc), and maximum energy product (BH)max after an optimum annealing treatment (933 K, 420 s) are 1.24 T, 263 kA/m, and 92 kJ/m3, respectively, for the Fe66.5Co9.5Nd3.5Dy0.5B20 alloy. The rather good hard magnetic properties are interpreted to result from the exchange magnetic coupling among 2:14:1, Fe3B, and α-(Fe, Co) phases. The good hard magnetic properties in the crystallized state of the Fe–Co–Nd–Dy–B amorphous alloys with large ΔTx over 40 K are expected to enable the future fabrication of a bulk hard magnetic material by the simple process of the formation of a bulk amorphous alloy followed by optimum crystallization. © 2000 American Institute of Physics.

    Nucleation Sites of Calcium Phosphate Crystals during Collagen Mineralization (2003)

    Notes: The nucleation sites of calcium phosphate crystals during collagen mineralization were studied by Fourier transform infrared spectrometry and transmission electron microscopy. It was found for the first time that there is another nucleation site, i.e., carbonyl (〉C=O) on collagen, besides the previous reported nucleation site of carboxyl (–COOH). By comparing the IR spectra of collagen not only with collagen/calcium phosphate but also with collagen/Ca2+, it was observed that the peak intensities of amides I, II, and III of collagen decreased significantly after mineralization. The decrease of the amide I peak intensity was mainly due to blockage of the C=O stretch. Furthermore, the peak for amide I gradually shifted to a lower wavenumber during collagen mineralization. This shift indicated that chemical interaction between carboxyl groups and Ca2+ ions formed in the mineralization.

    Cytoskeletal Changes in the Brains of Mice Lacking Calcineurin Aα (1997)

    Notes: Abstract: Hyperphosphorylated τ, the major component of the paired helical filaments of Alzheimer's disease, was found to accumulate in the brains of mice in which the calcineurin Aα gene was disrupted [calcineurin Aα knockout (CNAα−/−)]. The hyperphosphorylation involved several sites on τ, especially the Ser396 and/or Ser404 recognized by the PHF-1 monoclonal antibody. The increase in phosphorylated τ content occurred primarily in the mossy fibers of the CNAα−/− hippocampus, which contained the highest level of calcineurin in brains of wild-type mice. The CNAα−/− mossy fibers also contained less neurofilament protein than normal, although the overall level of neurofilament phosphorylation was unchanged. In the electron microscope, the mossy fibers of CNAα−/− mice exhibited abnormalities in their cytoskeleton and a lower neurofilament/microtubule ratio than those of wild-type animals. These findings indicate that hyperphosphorylated τ can accumulate in vivo as a result of reduced calcineurin activity and is accompanied by cytoskeletal changes that are likely to have functional consequences on the affected neurons. The CNAα−/− mice were found in a separate study to have deficits in learning and memory that may result in part from the cytoskeletal changes in the hippocampus.

    Epidemiological and aetiological studies on hair casts (1995)

    Notes: Hair casts (HC) appear to have become more common in young adults. An investigation on the incidence of HC was made in the Chengdu district of China. Of 3548 individuals surveyed, 30 24% suffered from HC. HC were restricted to females, among whom the incidence was 61.6%. HC is thus a very common finding. Long-term and frequent traction imposed on hair with excessive force appears to be the major cause of HC. This was confirmed from braiding studies which consisted of traction by tightly drawn braids un healthy subjects, together with histopathology of the underlying skin and statistical data on the frequency of HC.

    Colossal magnetoresistance behavior in LaCaMnO/CeO2/Si (100) multilayers grown by pulsed laser deposition (abstract) : The 41st annual conference on magnetism and magnetic materials (1997)

    Notes: The La–Ca–Mn–O (LCMO) system grown on lattice matched LaAlO3 substrates by pulsed laser deposition (PLD) has attracted much recent attention because of the colossal magnetoresistance exhibited. Interest in these materials is because of their potential application in the magnetic recording industry where one of the challenges is to integrate the chip signal-conditioning circuits together with the sensing elements. We have previously reported the giant magnetoresistance characteristics of La–Ca–Mn–O films grown on Si (100) substrates by PLD. Although magnetoresistance at 50 K under a field of 4.7 T was more than 35% (Δρ/ρ0), no colossal magnetoresistance values were present, clearly due to the imperfections introduced by the lattice mismatch between film and substrate. In this paper we report the transport properties and colossal magnetoresistance behavior in LCMO/CeO2/Si(100) multilayers grown by PLD. The CeO2 is attractive as a buffer layer due to its lattice constant, a, of 5.411 Å, which is close to that of silicon (the misfit factor, being only 0.35%). And by simply rotating the unit cell 45° in the basal plane, the mismatch is less than 0.16% with LCMO along the a–b plane. It is found that the LCMO/CeO2/ Si(100) multilayers also exhibit a well-defined peak of resistivity versus temperature, a similar behavior to a single LCMO layer on a Si substrate. A magnetoresistance value of more than 93% (Δρ/ρ0) was obtained at 77 K under a field of 12 T. The films have been characterized by vibrating sample magnometer, four-point probe and scaning tunneling microscopy, and details of the influence of the multilayer preparation parameter will also be discussed. ©1997 American Institute of Physics.
