摘要：

Superconductivity for lanthanide platinum boron carbide quaternary intermetallic phases is reported. For RPt2B2C, superconducting T(c)'s are approximately 10 K for R=La and Y and 6 K for R=Pr, reflecting the influence of magnetic pair breaking. The crystal structure for one of the analogs, LaPt2B2C, was determined by single-crystal x-ray diffraction. These materials are isostructural with the recently discovered RNi2B2C superconductors, but apparently can accommodate some nonstoichiometry. The density of states at the Fermi level for LaPt2B2C is estimated to be approximately 5 mJ/mole K2 through measurements of the critical fields and the normal-state susceptibility.
