概要
- 論文の詳細を見る
Electrical resistivity measurements of Cd_2Re_2O_7 under pressure and magnetic field have been performed. The two superconducting transitions previously observed under pressure become one under a magnetic field of 0.2 T. The superconductivity transition temperature T_c increases linearly from 1K to 2.4K with increasing pressure up to 2.4GPa in the field. The upper critical field H_<C2> observed by measurements of the field dependence of electrical resistivity under pressure increases to about 4T with increasing pressure up to 2.4 GPa. The Gruneisen parameters of T_c, H_<C2>, and T_s are estimated to be 96, 243, and -32, respectively.
