Magnetic Impurity States and Ferromagnetic Interaction in Diluted Magnetic Semiconductors
M. Ichimura, K. Tanikawa, S. Takahashi +2
The electronic structure of diluted magnetic semiconductors is studied, especially focusing on the hole character. The Haldane-Anderson model is extend to a magnetic impurity, and…

Cyclotron resonance in the quasi-1D organic superconductor (TMTSF)2ClO4
S. Takahashi, S. Hill, S. Takasaki +2
We report the observation of cyclotron resonance (CR) in a metal possessing pure quasi-one-dimensional Fermiology - namely, the organic linear-chain compound (TMTSF)2ClO4, whose Fe…

Crossed Andreev reflection in a d-wave superconductor with two quantum point contacts
S. Takahashi, T. Yamashita, S. Maekawa
We theoretically study the crossed Andreev reflection in a hybrid nanostructure which comprises a d-wave superconductor and two normal-metal quantum wires. When the superconductor…
