Abstract

Using an ac susceptometry technique, H-T phase diagrams were determined for various Pt contents in the noncentrosymmetric superconducting system Li 2(Pd1-xPtx)3B, from which several superconducting parameters could be extracted. Despite the end compositions having very different band and gap structure and despite a change from singlet- to triplet-dominant pairing, these superconducting parameters change continuously with cation substitution. Weak-coupling BCS and Ginzburg-Landau relations appear to be obeyed, suggesting that this may be a particularly uncomplicated system for studying the effect of a lack of inversion symmetry.
