Abstract :
It is shown experimentally that amorphous films of U-Sb and films with 20% Co and Mn added are all ferromagnetic with Curie temperatures as high as 135 K with magnetic moments per uranium of up to 1.4 μB. Magnetooptical polar Faraday and Kerr rotations at 10 K and 40 kOe have values up to +2×106°/cm and -3°, respectively. The magnetooptical rotation correlates with Hall angles of up to 17°. It is suggested that U-Sb magnetooptical effects and Hall effects are due to an intraband transition
