Heavy fermion superconductivity and magnetic order in noncentrosymmetric CePt3Si -: art. no. 027003

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 T(N)approximate to2.2 K and enters into a heavy fermion superconducting state at T(c)approximate to0.75 K. Large values of H(c2)(')approximate to-8.5 T/K and H-c2(0)approximate to5 T refer to heavy quasiparticles forming Cooper pairs. Hitherto, CePt3Si is the first heavy fermion superconductor without a center of symmetry.
