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