Investigation of Bulk Superconductivity in PrPt₅

We performed µSR measurements on a polycrystalline sample of PrPt₅ from 70 K down to 50 mK in order to clarify whether PrPt₅ shows bulk superconductivity or not. Unfortunately, strong local field and very low upper critical field made it difficult to characterize possible superconductivity in PrPt₅. On the assumption that the superconductivity is realized over the whole specimen, the lower limit of the magnetic penetration depth is estimated to be 540 nm.
