文摘

Superconducting cubic 未-MoC_0.75 has been synthesized by a high-pressure synthesis method at a pressure of 17 GPa in a Kawai-type instrument, followed by studies on the crystal structure by synchrotron X-ray diffraction. Electromagnetic measurements indicated a superconducting transition temperature T_c of 14.3 K, which is the highest T_c value experimentally confirmed among the binary metal carbides. The cubic 未-MoC_0.75 prepared in this study could be considered as a weakly coupled superconductor.
