Abstract

PURPOSE:To obtain high coercive force film material which has coercive force more than 500Oe, residual flux density more than 5,000G(Gauss) and square ratio more than 0.85 by a method wherein Co-nitride is deposited into Co-base of an alloy which has 3-40atomic% N and remainder of Co. CONSTITUTION:This film material is obtained by depositing Co-nitride into Co- base of alloy which has 3-40atomic% of N and remainder of Co, or by depositing Co-nitride and Ni-nitride into Co-Ni base of alloy which has 3-40atomic% of N, 0.1-48.5atomic% of Ni and remainder of Co and has Ni content not more than Co content. This deposition of the nitride can be obtained by heating the alloy film, which is formed by vacuum evaporation, in atmosphere of inert gas such as Ar or He which contains 1-100% of N-gas at 250-700 deg.C temperature for 1min-200hr.
