    Notes: Previously Tsuchiya and Uematsu reported their discovery of a photoinduced effect in which the decrease ΔHp of ferromagnetic resonance field of surface spin-wave modes in the H+2 -implanted layer of YIG thin films is observed during light irradiation at 77 K, and etching depth dependence of ΔHp is measured. The decrease ΔHp in as-implanted films is attributed mainly to generation of Fe2+ ions with hydrogen presence. The main hydrogen distribution has been introduced from the study.1 Here the authors describe ΔHp relaxation as the irradiation is turned on and off in the cases of as-implanted films and films covered with a sputtered SiO2 layer, before and after annealing. (111)-oriented YIG films are used. The energy of H+2 implantation is 30 keV and the dose is 1×1016 ions per cm2. The FMR frequencies are 9.2–9.4 GHz. First, an as-implanted film is irradiated for 10 min without applying a magnetic field and then after removing the irradiation ΔHp is able to be observed (class II). Next, ΔHp is measured to increase during irradiation with a field (class I), and then after removing ΔHp decreases to a class II level. Class I and II are explained from "one-center model'' and "two-center model'' of photoinduced magnetic anisotropy effect,2 respectively. Relaxation of ΔHp mentioned above, as well as that of ΔHp about films covered with SiO2 are measured and their particular properties are discussed.

    Notes: For the first time, the oscillation wavelength and the laser structure dependence of the K factor and of the nonlinear gain suppression coefficient ε in semiconductor lasers were systematically investigated. As a result, we suggest that the nonlinear gain effect can be explained by the spectral hole burning theory.

    Notes: We examine the direct bonding of (001) InP and (110) GaAs and demonstrate its application to device fabrication. Cross-sectional observation shows that these wafers can be united without generating dislocation. (001) InP-based 1.55-μm wavelength lasers are fabricated on (110) GaAs. The light–current characteristics of the lasers are almost identical to those of lasers fabricated on (001) GaAs, while the turn-on voltage is higher by about 0.4 V due to the large band discontinuity. The results show that the direct bonding technique is promising for allowing new concept "free-orientation integration.'' © 1995 American Institute of Physics.

    Systematics of elasticity: Ab initio study in B1-type alkaline earth oxides (2001)
    College Park, Md. : American Institute of Physics (AIP)

    Notes: The elastic properties and their pressure dependence of four B1-type alkaline earth oxides, MgO, CaO, SrO, and BaO, are calculated using the ab initio full-potential linear muffin-tin-orbital (FP-LMTO) generalized gradient approximated (GGA) method to elucidate their systematics. The calculated results agree quite well with the comparable experimental data. The large pressure dependence of c11 and c44 of MgO observed over 25 GPa is not predicted as well as the previous local-density approximation (LDA) calculations. It is inferred that the high-pressure measurement of elastic constant is quite sensitive to nonhydrostaticity. The deviation from the Cauchy relation and the elastic anisotropy are investigated. It is found that the interatomic interaction in SrO is nearest to the two-body force and the many-body contribution is largest in MgO. The elastic anisotropy in SrO and BaO are almost the same and only MgO has a large positive anisotropy under low pressure. The normalized elastic constants cij′ are introduced for more detail analysis. It is found that while there is no substantial difference in c11′ and c12′ of the four oxides, only c44′ and its pressure dependence vary systematically. The difference in the Cauchy deviation and elastic anisotropy of alkaline earth oxides under pressure is characterized by c44. © 2001 American Institute of Physics.

    Crystal growth and fabrication of a 1.3-μm-wavelength multiple-quantum-well laser on a (211)A InP substrate (1997)

    Notes: We demonstrate the fabrication of a long-wavelength laser on a (211) InP substrate, with the expectation of reducing threshold current density. We found that InGaAsP single quantum wells (SQWs) could be fabricated with good optical properties provided the SQW layers were not made too thin. A laser that had an unstrained multiple-quantum-well active layer emitting at 1.3 μm was fabricated on a (211)A InP substrate. Its threshold current density was 900 A/cm2, which is comparable to the value for the same type of laser on a (100) substrate. These results suggest that long-wavelength lasers with satisfactory quality can be fabricated on a (211)A substrate. © 1997 American Institute of Physics.

    Notes: The recovery in cutaneous barrier functions, assessed in terms of transepidermal water loss, 1 h after tape stripping of volar forearm skin in human volunteers, was investigated at different times over the 24 h day. The barrier recovery rate was significantly lower between 20:00 h and 23:00 h than that at other time points. The skin surface temperature and the basal transepidermal water loss reached their highest values at about 03:00 h (33·6 °C and 0·30 mg cm−2 h−1), while the cortisol level in the saliva was highest at 09:00 h (7·8 pmol mL−1). These results suggest significant time-dependent variation in cutaneous barrier repair independent of changes in skin temperature and cortisol level.

    Mitigation of stress-induced suppression of contact hypersensitivity by odorant inhalation (2001)

    Notes: Background Various skin functions are affected by stress. We have previously shown that odorant inhalation can regulate skin immune reactions. Objectives To test the hypothesis that certain odorants can mitigate the effects of stress on skin immune reactions. Methods Contact hypersensitivity (CH) reactions were elicited in C57BL/6 mice. Mice were subjected to immobilization stress and were exposed to odorants for 2 days. Epidermal sheets were stained for I-A antigens and analysed by confocal laser scanning microscopy. Serum corticosterone levels were assayed by radioimmunoassay. Results Exposure of mice to 1,3-dimethoxy-5-methylbenzene (DMMB) had no effect on the intact CH reaction, but it upregulated the reaction suppressed by immobilization stress. Other odorants, including terpinyl acetate and valerian oil, had minor effects on the CH reaction. Suppression of I-A-positive cells was prevented by DMMB inhalation. Valerian oil, but not DMMB, downregulated stress-induced plasma corticosterone levels. Conclusions Results suggest that odorant inhalation modulates various physiological pathways, some of which result in regulation of skin function.

    Notes: Chromosomes of 11 cultivars of Alstroemeria were studied to determine their somatic constitutions. Two cultivars, ‘Eureka’ and ‘Zebra’, were diploid (2n = 2×= 16), six cultivars, ‘Yellow King’, ‘King Cardinal’, ‘Mona Lisa’, ‘Appelbloesem’, ‘Pink Triumph’ and ‘Rosita’ were triploid with 2n = 3×= 24, one cultivar, ‘Orange Beauty’ was a hypertriploid (2n = 3×+ 1 = 25), one cultivar, ‘Luciana’ was a hypotetraploid (2n = 4×– 1 =31) and one cultivar, ‘Jubilee’, was true tetraploid (2n = 4×= 32). This result suggests that polyploid cultivars may have more market value in this cut flower, Alstroemeria.

    Nematode Resistance and Meiotic Abnormality in Diploid Sugar Beet Selected from Interspecific Beta vulgaris×B. procumbens Hybrids (1988)

    Notes: Two nematode-resistant trisomic lines which were derived from interspecific Beta, vulgaris × B. procumbens hybrids were intercrossed or backcrossed with susceptible diploid sugar beer and their progenies were screened for nematode resistance. The transmission rate of resistance varied from 1.5 % to 47.6 % with an average of 20.4 % in the progenies of individual insomics derived from the two trisomic lines. Eleven resistant diploads were selected with a frequency of 0.2 %. These resistant diploids were classified into two groups, i.e., one group showed relatively high transmission rates of resistance with an average of 25.4 % and the other extremely low with an average of 1.2 % in their backcrossed and s el fed progenies., Meiotic chromosome behavior in a resistant diploid group with high transmission rates was considerably normal as compared to that in a resistant diploid group with low transmission rates. Chromatid bridges and acertric fragments were detected in 93 % of resistant diploids and in 46 % of susceptible diploids. Two different sized fragments occurred in resistant diploids, while only a smaller fragment was present in susceptible diploids. A frequency of sporocytes with bridges-fragments was 17.4% at anaphase I and 13.9 % at anaphase II in resistant diploids, while in susceptible diploids a frequency was 2.9 % and 5.3 % at the respective stages. These results suggest that at least two paracentric inversions are present in resistant diploids, one of which is linked to nernatode resistance and may be responsible for the low transmission rate of resistance.
