Abstract

Bulk studies of UPt show clearly that this material orders magnetically below 28 K. In contrast to numerous previous studies we found that the low-temperature properties can be explained only by the presence of an energy gap (22-35 K) in the dispersion relation of magnons which leads to typical exponential temperature dependencies of magnetic, thermal and electrical transport properties. Another magnetic phase transition around 19 K, found by means of magnetization measurements on an as-cast sample, is most likely due to the presence of a minority phase.
