Emergence of a superconducting state from an antiferromagnetic phase in single crystals of the heavy fermion compound Ce2PdIn8

Abstract

Single crystals of Ce2PdIn8 were studied by means of magnetic susceptibility, electrical resistivity and specific heat measurements. The compound was found to be a heavy fermion clean-limit superconductor with Tc = 0.68 K. Most remarkably, the superconductivity in this system emerges out of the antiferromagnetic state that sets in at TN = 10 K, and both cooperative phenomena coexist in a bulk at ambient pressure conditions.
