Magnetic, transport and magneto-optical properties of U/sub x/Sb/sub 1-x/ amorphous films

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 mu /sub B/. Magnetooptical polar Faraday and Kerr rotations at 10 K and 40 kOe have values up to +2*10/sup 6/ degrees /cm and -3 degrees , respectively. The magnetooptical rotation correlates with Hall angles of up to 17 degrees . It is suggested that U-Sb magnetooptical effects and Hall effects are due to an intraband transition.<
