Abstract
The invention relates to a garnet film for an ion-implanted device characterized in that the quantity of Fe is increased and a predetermined quantity of Gd is added. The garnet film of the invention has a sufficiently high Curie temperature without sacrificing its other properties and hence is extremely suitable as a garnet film for an ion-implanted device.
