The results of magneto-optical investigations into the Γ2–Γ4 spin reorientation in an Sm0.6Tb0.2Tm0.2FeO3 orthoferrite single crystal are reported. The magneto-optical parameters are determined taking into account the dichroism. The orientation of the antiferromagnetic vector in the canted phase is investigated as a function of the magnetic field and temperature. The magnetic anisotropy field strengths are determined by the processing of the results. The orientation contribution to the birefringence is estimated. 相似文献

The structure of 65SnF2-35GaF3, 75SnF2-25GaF3, and 85SnF2-15GaF3 glasses is studied using Raman and IR spectroscopy. The glass structure in the SnF2-GaF3 system is formed by a mixed network of fluorogallate and fluorostannate groups. A boson peak is observed in the low-frequency region (~29 cm?1) of the Raman spectra of the glasses. The shape of the boson peak signifies that the glass does not separate into components on the nanometer scale. 相似文献

Images of cleaved surfaces were obtained for 53ZrF4-20BaF2-4LaF3-3AlF3-20NaF (ZBLAN) glasses and fused quartz using an NTMDT atomic force microscope. It is shown that the scatter of particle size depends on the cooling rate and is 21–48.5 Å for the cleaved surface of ZBLAN glass obtained by very fast cooling and 68–172 Å for the cleaved surface of ZBLAN after slow cooling. For cleaved fused quartz, the range is 25-18 Å. 相似文献

This paper describes simple algorithms for evaluating gamma-ray spectra, readily applicable to small computers. A comparative
assessment of the accuracy of the existing programs for experimental data analysis is presented. The use of “Nairi-K” computers
suitable for “on-line” operation with multichannel analyzers enables as many as 300 element determinations to be carried out
in a 7-hour working day. 相似文献

Orbital relaxation (OR) amounts to variation of the orbital exponents in hydrogen molecules and ions relative to the exponents of the isolated atom; it is represented as the sum of the one- and two-center contributions depending on the effective atomic charge and on the presence of other atoms in the molecule. The procedure for isolating the contributions of the exponent includes treatment of the OR of hydrogen in a special set of neutral and charged atoms and molecules with certain multiplicities of their electronic states. Within the framework of the spin-unrestricted Hartree-Fock method, we found and discussed the optimal values of the exponents of the basis orbitals of hydrogen atoms and molecules using the minimal split valence-shell basis set, the basis set that includes the polarization function, and the expanded set of grouped natural orbitals. A simple energy model is suggested for OR. Expressions are derived for evaluating the exponents of the relaxed orbitals in hydrogen-containing systems.Original Russian Text Copyright © 2004 by A. I.
