Abstract

The temperature dependences of the parallel and perpendicular critical magnetic fields of polycrystalline Ube13 films have been measured. The ratio of the critical fields, Hc11/Hc⊥, has been found to be 1.25 at low temperatures, a value less than would be expected for s-wave pairing without surface pair-breaking but greater than expected for any pairing configuration which is a pure angular momentum state with L ≠ 0. Similar efforts directed at the preparation of UPt3 films were unsuccessful because of the formation of an impurity phase of UPt which is a ferromagnet.
