Abstract
Ternary metal phosphides MRuP (M = Mo or W) with a Co2P-type structure and MNiP(M = Mo or W) with a Fe2P-type structure have been prepared at around 1 600 degreesC and 4 GPa. The electrical and magnetic properties of these com pounds were studied at low temperature. The superconductivity of these comp ounds is observed at around 15.5 K for the molybdenum phosphides, and at 5 K fur the wolfram phosphides. These are new superconductors. Both ternary m olybdenum phosphides have the highest T-c among the metal phosphides. (C) 2 000 Elsevier Science Ltd. All rights reserved.
