Abstract

Topological properties of the Fermi surfaces of UIr3 and UGe3 were investigated. UIr3 is an uncompensated metal with open orbits along 〈110〉. This is in agreement with a proposed model of Arko and Koelling, based on augmented-plane-wave (APW) calculations. UGe3 is a compensated metal, which showed nearly quadratic magnetoresistance behavior for all field directions studied. The results are compared with the APW model of Arko and Koelling, which contains a multiply connected sheet of Fermi surface. The model, or slight variations thereof, is consistent with the available data.
