Abstract
The switching behavior of amorphous GdTbFe magneto-optic storage layers has been investigated as a function of compensation temperature. Films with Curie temperature ranging from 420 K to 495 K and compensation temperatures ranging from 200 K to 420 K exhibit writing behavior with carrier-to-noise ratio up to 61 dB. Outside this range poor quality films are obtained.
