Topological properties of the Fermi surfaces of UIr/sub 3/ and UGe/sub 3/ were investigated. UIr/sub 3/ 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. UGe/sub 3/ 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 available data.
