OSTI ID:5378629
Superconductivity and magnetism in the new group of rare-earth ternary borides, MRh/sub 4/B/sub 4/, has been reported recently by Matthias et al. Particularly striking has been their observation of reentrant magnetism accompanying the return to a normal state at low temperatures (T = 0.9/sup 0/K) in the superconductor ErRh/sub 4/B/sub 4/ which has a superconducting transition temperature of 8.5/sup 0/K. We discuss the origin of superconductivity and magnetism in these systems using results of ab initio self-consistent LMTO energy band calculations for the alloys M = Y, Er and Ho.
