Abstract

PURPOSE:To improve corrosion resistance by chemically adsorbing metallic salt of perfluoroalkyl carboxylic acid onto a magnetic thin film of alloy. CONSTITUTION:A magnetic thin film made of cobalt or its alloy, etc., is coated with a solution of metallic salt, such as chrominum, nickel, copper, etc., of perfluoroalkyl carboxylic acid (CnF2n+1COOH: n>=1), an organic solvent solution, or a dispersant to adsorb said metallic salt chemically.
