Abstract

The compound ErRh4B4 becomes superconducting at a critical temperature Tc1 of 8.7 K followed by a return to the normal state at a second critical temperature Tc2 of 0.9 K. The return to the normal state at Tc2 is coincident with the occurrence of long-range ordering of the magnetic moments of the Er3+ ions which completely occupy a set of equivalent lattice sites.
