摘要: Abstract We report the observation of superconductivity in intermetallic thorium-based boride carbides. For ThM2B2C, superconducting Tc's 6 K (M=Ni), 6.5 (M=Pt), and 14.5 (M=Pd) have been measured. These compounds are isostructural with recently reported LnNi2B2C superconductors. also observed bulk an as-yet-undetermined thorium-palladium-boron-carbon quaternary phase at 21.5 K. Critical-field measurements on two palladium-based superconductors, as well pressure dependence Tc for superconductor, reported.
