文摘

Physical and superconducting nature of LaRu2M2 (M = P and As) have been studied. LaRu2P2 is brittle in nature while LaRu2As2 demonstrates the ductile nature. LaRu2P2 is relatively harder than that of LaRu2As2 intermetallic. Tc of LaRu2P2 is calculated to be 10.18 K. Both the compounds are phonon-mediated medium coupled BCS superconductors.
