Coexistence of superconductivity and long-range magnetic order inErPd2Sn

Abstract
Heat-capacity, magnetic-susceptibility, resistivity, and alloying experiments indicate that long-range magnetic order and superconductivity coexist below ∼1 K in a well-ordered, homogeneous sample of ErPd2Sn. The sample enters the superconducting state at Tc=1.17 K followed by magnetic order at TM=1.00 K. The superconducting state is retained to 40 mK, the lowest temperature attained.
