Abstract
High field magnetic studies on amorphous Fe72-xYxHo8B20 alloys have be en performed at 4.2 K for fields up to 35 T. The results arc interpret ed in terms of a model originally proposed for crystalline materials. The critical field at which the antiferromagnetic coupling becomes uns table is well predicted by the model. The exchange integral J(Ho-Fe) i ncreases with a decrease in Fe moment.
