Valence-band structures of U3Ni3Sn4, U3Ni3Sb4, U3Cu3Sn4 and U3Cu3Sb4 ranging from a semiconductor to a heavy fermion system, are studied using photoemission spectroscopy with synchrotron radiation. We found that the Ni3d band in U3Ni3Sn4 is not fully

We present results of magnetic, transport and calorimetric measurements on U 3 T 3 X 4 with T=Ni, Cu, Pd, Pt and Au and X=Sn and Sb. A heavy-fermion behavior manifests itself in U 3 T 3 Sn 4 , where the electronic specific-heat coefficient increases

A non-magnetic semiconducting to ferromagnetic metal transition appears around x = 0.20 in U3(Ni1−xCux)3Sb4 with a cubic Y3Au3Sb4-type structure. Above x = 0.20, both the spontaneous moment per U atom and TC monotonically increase with increasing x
