Abstract

A novel iron-base soft magnetic alloy having excellent soft magnetism, particularly a low coercive force and a high permeability in a high-frequence range, and low iron loss, This alloy. is produced by adding a given amount of aluminum and preferably further given amounts of elements such as niobium to an Fe-Si-B alloy to give an amorphous alloy, forming the alloy into thin belt, powder, thin film; etc., and heat treating the resulting alloy, thus giving an alloy composed of at least 30 % of a crystalline portion and the balance of an amorphous portion.
