PURPOSE:To produce an Fe-Si-base alloy for vapor deposition which is adequate for forming a thin film to be used as a magnetic recording material by incorporating specific ratios of Si, Al, Ti, Ca, O, S, and N into Fe. CONSTITUTION:The Fe-Si-base alloy contg. 2.5-10wt.% Si, 0.005-0.5wt.% Al, and/or <=0.5wt.% Ti, 10-100ppm Ca, <=50ppm, more preferably <=20ppm O, <=20ppm, more preferably <=10ppm S, <=30ppm, more preferably <=10ppm N and consisting of the balance substantially Fe is prepd. Other impurities in the alloy are decreased as far as possible and are, for example, confined to about <=0.005% Mn and about <=50ppm P. The Fe-Si-base alloy useful as the material for producing the thin film of the magneto-optical recording material is thereby obtd.
