Studies of stress, composition, and magnetic resonance have been made on amorphous Gd--Co thin films implanted with nitrogen ions at fluences between 10/sup 10/ and 10/sup 16/ ions/cm/sup 2/. A new mode of magnetic resonance is produced in a small portion of the implanted region. In this portion H/sub A/ - 4..pi..M decreases with fluence and ultimately achieves a negative value considerably larger in magnitude than 4..pi..M in the film prior to the implantation. This behavior is interpreted as arising from a decrease in the Gd--Co exchange interaction which reduces the alignment of the Gd spin system.
