Evidence for Carrier-Induced High-Tc Ferromagnetism in Mn-doped GaN film

S. Yoshii, S. Sonoda, T. Yamamoto +6

A GaN film doped with 8.2 % Mn was grown by the molecular-beam-epitaxy technique. Magnetization measurements show that this highly Mn-doped GaN film exhibits ferromagnetism above r…

Evolution of the electronic structure across the filling-control and bandwidth-control metal-insulator transitions in pyrochlore-type Ru oxides

J. Okamoto, S. -I. Fujimori, T. Okane +4

We have performed photoemission and soft x-ray absorption studies of pyrochlore-type Ru oxides, namely, the filling-control system Sm $_{2 - x}$ Ca $_{x}$ Ru $_{2}$ O $_{7}$ and the bandwidth-con…

Optical investigations on $Y_{2 - x} B i_{x} R u_{2} O_{7}$ : Electronic structure evolutions related to the metal-insulator transition

J. S. Lee, S. J. Moon, T. W. Noh +4

Optical conductivity spectra of cubic pyrochlore $Y_{2 - x} B i_{x} R u_{2} O_{7}$ (0.0 $\leq$ {\it x} $\leq$ 2.0) compounds are investigated. As a metal-insulator transition (MIT) occurs arou…

Unconventional Upper- and Lower-Critical Fields and Normal-State Magnetic Susceptibility of the Novel Superconducting Compound $N a_{0.35} C o O_{2} \cdot 1.3 H_{2} O$

Hiroya Sakurai, Kazunori Takada, Shunsuke Yoshii +3

Magnetic properties of the novel layered superconductor, Na $_{0.35}$ CoO $_{2}$ $\cdot$ 1.3H $_{2}$ O have been investigated. From the temperature dependence and field dependence of the…
