The magnetic and magneto-optic characteristics of indium (In) -alloyed TbFe amorphous films are investigated. Alloying with In drastically decreases the compensation temperature, and increases the Kerr rotation by more than 20%. Both the compensation composition and the compensation temperature are observed to shift to the Tb-rich side when alloying with In. These magnetic property changes are attributed to the influence of In on the Fe and/or Tb moments.
