Abstract :
Multilayers of crystalline Co and amorphous U-As were prepared by magnetron sputtering. The number of Co/U-As bilayers varied from 30 to 170. The magnetooptical, magneto-transport, and magnetic properties are reported for Co layer thickness varying from 2 to 10 Å and U-As from 5 to 30 Å. The properties of the multilayer films are different from the properties of films of U-As, Co and an U-As-Co alloy. Some exchange coupling between the Co and U-As at 300 K is observed from polar Kerr measurements for films with U-As layers 20 Å and thicker
