Direct observation of localization in the minority-spin-band electrons of magnetite below the Verwey temperature
H. Kobayashi, T. Nagao, M. Itou +5
Two-dimensional spin-uncompensated momentum density distributions, s, were reconstructed in magnetite at 12K and 300K from several measured directional mag…
Role of Oxygen Electrons in the Metal-Insulator Transition in the Magnetoresistive Oxide LaSrMnO Probed by Compton Scattering
B. Barbiellini, A. Koizumi, P. E. Mijnarends +7
We have studied the [100]-[110] anisotropy of the Compton profile in the bilayer manganite. Quantitative agreement is found between theory and experiment with respect to the anisot…
Phase competitions and coexistences in quasi-one-dimensional molecular conductors: exact diagonalization study
Yuichi Otsuka, Hitoshi Seo, Yukitoshi Motome +1
We investigate ground state properties of a quasi-one-dimensional electron-lattice coupled model for quarter-filled molecular conductors. The effective one-dimensional extended Hub…
Point-contact spectroscopy of the heavy-fermion superconductor CePtSi
R. Onuki, A. Sumiyama, Y. Oda +3
Differential resistance spectra ( characteristics) have been measured for point-contacts between the heavy-fermion superconductor (HFS) CePtSi and a norm…
