High superconducting transition temperatures of new rare earth ternary borides.
A new group of ternary borides has been found that show either ferromagnetism or superconductivity. Their general formula is MRh(4)B(4) where M is a transition or rare-earth element. Their superconducting transition temperatures range from approximately 2.5 K for the Sm compound to approximately 12 K for the Lu compound.
