概要 A layered compound CePd5Al2, which is an analog of a heavy fermion superconductor NpPd5Al2, is found to be an antiferromagnet with an easy-axis along the tetragonal [001] direction but becomes superconductive in the pressure region from 9 to 12GPa, with the superconducting transition temperature, T-sc = 0.57 K and the upper critical field at 0 K, H-c2(0) = 2.5 kOe, at 10.8 GPa. The quasi-two dimensional Fermi surfaces are also theoretically calculated for CePd5Al2 on the basis of the 4f-itinerant band model.
