Origin and control of high-temperature ferromagnetism in semiconductors
Shinji Kuroda, Nozomi Nishizawa, Koki Takita +4
The extensive experimental and computational search for multifunctional materials has resulted in the development of semiconductor and oxide systems, such as (Ga,Mn)N, (Zn,Cr)Te, a…
Dynamic ordering of driven vortex matter in the peak effect regime of amorphous MoGe films and 2H-NbSe2 crystals
N. Kokubo, T. Asada, K. Kadowaki +3
Dynamic ordering of driven vortex matter has been investigated in the peak effect regime of both amorphous MoGe films and 2H-NbSe2 crystals by mode locking (ML) and dc transport me…
Significant enhancement of ferromagnetism in ZnCrTe doped with iodine as an n-type dopant
Nobuhiko Ozaki, Nozomi Nishizawa, Stephane Marcet +3
The effect of additional doping of charge impurities was investigated in a ferromagnetic semiconductor ZnCrTe. It was found that the doping of iodine, which is expect…
Peak effect and dynamic melting of vortex matter in NbSe crystals
N. Kokubo, K. Kadowaki, K. Takita
We present a mode locking (ML) phenomenon of vortex matter observed around the peak effect regime of 2H-NbSe pure single crystals. The ML features allow us not only to trace ho…
Anisotropic Optical Conductivity of Nd2-xCexCuO4 Thin Films
Takashi Yanagisawa, Shigeru Koikegami, Hajime Shibata +5
Opticcal conductivity spectra of Nd2-xCexCuO4 thin films, measured by the reflectance-transmittance method (R-T method) which has been proposed to investigate far-infrared…
