Autor: Norikazu Tanaka, Haruki Shoren, Fumihiko Ikemoto, Kazuko Motizuki, Kouki Yoshida
Publikováno v: Physica E: Low-dimensional Systems and Nanostructures. 10:242-246
Electronic band structure of magnetic semiconductors based on II–VI compounds such as Zn1−xCrxX (X=Te, Se, S; x=1, 0.5, 0.25) are calculated for non-magnetic (NM), ferromagnetic (F) and antiferromagnetic (AF) states by using the full-potential li

Publikováno v: Journal of the Physical Society of Japan. 68:2067-2072
We have measured the de Haas–van Alphen effect at 0.55 K in the field up to 9.5 T for the single crystal of Pauli paramagnetic NiAs. Six dHvA branches have been observed and they show complicated behavior as a function of the field direction which

Electronic Structure and Magnetic Properties of Li2CuO2
Autor: Kazuko Motizuki, Masakatsu Suzuki, Norikazu Tanaka
Publikováno v: Journal of the Physical Society of Japan. 68:1684-1692
Magnetic properties of Li 2 CuO 2 are investigated from the both sides of localized electron picture and of itinerant electron picture. First, the anisotropy of g-factor of Cu 2+ ion is studied by calculating the orbital level splitting of Cu 2+ ion

Anisotropy of g-Factor and Magnetic Anisotropy Energy of Antiferromagnetic Cu-Compound Bi2CuO4
Autor: Norikazu Tanaka, Kazuko Motizuki
Publikováno v: Journal of the Physical Society of Japan. 67:1755-1761
To study the anisotropy of g-factor of Cu 2+ ion in the antiferromagnetic Bi 2 CuO 4 having an interesting crystal structure, we calculate the energy splitting of the orbital state of Cu 2+ ion due to the electric crystalline field arising from the s

Effect of intercalation on structural instability and superconductivity of layered 2H-type NbSe2 and NbS2
Autor: Kazuko Motizuki, Yoshimasa Nishio, Naoshi Suzuki, Masafumi Shirai
Publikováno v: Journal of Physics and Chemistry of Solids. 57:1091-1096
Effects of intercalation on the lattice instability and the superconductivity of NbSe2 and NbS2 are studied in the framework of the rigid band approximation. In the case of doping acceptor-type intercalants into NbSe2, the point of lattice instabilit

First-principles calculation of optical conductivity of FeSe and CoSe
Autor: Hiroaki Ikeda, Kazuko Motizuki, Naoshi Suzuki, Masafumi Shirai
Publikováno v: Journal of Electron Spectroscopy and Related Phenomena. 78:91-94
The absorption spectra Iα(ω) (α = x, y, z) due to inter-band transitions are calculated for NiAs-type FeSe and CoSe by evaluating the matrix elements of the dipole-transition with use of the wave functions obtained by the LAPW band calculations. I
