摘要
We have reinvestigated the Hall effect and the magnetoresistance of UNiSn in a high-quality sample. Analysis of the results indicate the presence of at least three different types of carriers in the semiconducting state and a complex behavior at the transition from paramagnetic semiconductor to antiferromagnetic metal. Contrary to the expected result we observed only small changes in the carrier concentration but a large increase in the mobility.
