YPtBi: a possible half-Heusler unconventional superconductor

musr_ssc In this publication we report new results on the low-field magnetic response of the non-centrosymmetric superconductor YPtBi (Tc 0.77 K) in Solid state communications. We find a surprisingly small lower critical field. From muon spin rotation experiments we are able to deduce an upper bound of 0.04 mT on the spontaneous magnetic field associated with a possible odd-parity component in the superconducting order parameter.
