Magnetooptical study of uranium additions to Amorphous Tb(x)Fe (1-x).
01 January 1987
Recent reports of huge magnetooptical Kerr effects in certain crystalline metallic uranium compounds prompted a study of the magnetic and magnetooptical effects of uranium additions to a rare earth-transition metal amorphous alloy. Using variable composition samples, the polar Kerr effect at a small spot (e.g. 0.5mm diameter) was measured as field, temperature, and composition were varied. Points on the Curie line and the edges of the compensation region were determined from these observations. The compositions studied included, (Tb(x)Fe (1-x))(1-y)U(y) with 0.125
