In-gap state and effect of light illumination in CuIrS probed by photoemission spectroscopy
K. Takubo, T. Mizokawa, N. Matsumoto +1
We have studied disorder-induced in-gap states and effect of light illumination in the insulating phase of spinel-type CuIrS using ultra-violet photoemission spectroscopy (…
Novel Magnetic and Thermodynamic Properties of Thiospinel Compound CuCrZrS
Masakazu Ito, Hiroki Yamamoto, Shoichi Nagata +1
We have carried out dc magnetic susceptibility, magnetization and specific heat measurements on thiospinel CuCrZrS. Below 58 K, dc magnetic susceptibility a…
Large negative magnetoresistance in thiospinel CuCrZrS4
Takao Furubayashi, Hiroyuki Suzuki, Nami Kobayashi +1
We report on large negative magnetoresistance observed in ferromagnetic thiospinel compound CuCrZrS. Electrical resistivity increased with decreasing temperature according to…
Ionic Ordering in Thiospinel CuIrS
T. Furubayashi, T. Matsumoto, S. Nagata
Crystal structure of spinel compound CuIrS was examined by powder X-ray diffraction for the insulating phase below the metal-insulator transition at = 230 K. T…
