Заглавие : Studying the electronic structure of Cr (x) Ti(1-x) Se(2) by X-ray resonance and absorption spectroscopy Место публикации : Journal of experimental and theoretical physics. - 2011. - Vol. 112, № 1. - С. 87-93 Примечания : Bibliogr. : p. 93 (19 ref.) ББК : 54 Предметные рубрики: ХИМИЧЕСКИЕ НАУКИ Аннотация: Cr (x) Ti(1 - x) Se(2) (x = 0-0.83) solid solutions have been synthesized. Single crystals have been grown in the range of concentrations x = 0-0.83. Structural studies of samples have revealed that chromium atoms substitute titanium in the TiSe(2) matrix. The X-ray photoelectron spectra of the core levels, the resonance spectra of the valence bands in 1T-Cr (x) Ti(1 - x) Se(2), and the X-ray absorption spectra of titanium and chromium are studied. The titanium and chromium atoms are shown to have oxidation numbers of +4 and +3, respectively, in an identical octahedral environment. The local density of chromium states has been calculated. The results of the calculation agree well with the experimental data and indicate that the electronic 3d states of chromium substituting titanium in the matrix are spin-polarized and the density of chromium states is halfmetal magnet in behavior Держатели документа: Центральная научная библиотека УрО РАН Доп.точки доступа: Shkvarin, A.
