Magnetic and transport properties of amorphous U-As-Cu films

The addition of Cu to amorphous U-As films lowers the resistivity and extends the compositional range of ferromagnetism. Although the saturation magnetization of these materials is small, they have large coercive fields, anomalous Hall effects and magneto-optical rotations which may be due in part to strong spin-orbit interactions. The uranium f-d transition found in the binary U-As is depressed and broadened by Cu. © 1992.
