Abstract
CePt3Si is a novel heavy fermion superconductor, crystallizing in the CePt3B structure as a tetragonally distorted low symmetry variant of the AuCu3 structure type. CePt3Si exhibits antiferromagnetic order at TN≈2.2 K and enters into a heavy fermion superconducting state at Tc≈0.75 K. Large values of Hc2′≈−8.5 T/K and Hc2(0)≈5 T refer to heavy quasiparticles forming Cooper pairs. Hitherto, CePt3Si is the first heavy fermion superconductor without a center of symmetry.
