Abstract: PURPOSE:To secure and stabilize a high sigmas (magnetic saturation) while a good stability against oxidation is being kept by a method wherein the surface is oxidized uniformly up to a metastable state and, after that, heated and annealed. CONSTITUTION:A magnetic metal powder which is composed mainly of iron is made to flow by using an inert gas at a constant temperature of room temperature to 120 deg.C; oxygen gas is mixed continuously in such a way that an increase rate in the concentration of oxygen is 10 to 2000ppm/min. When a temperature inside a fluid layer reaches its peak and/or when oxygen is detected in a gas at the exit side, a supply operation of oxygen is stopped. After that, the temperature inside the layer is heated up to 150 to 600 deg.C and is held for 0.2 to 24hrs; after that, the layer is cooled; the oxygen is mixed continuously by the same method. When the temperature inside the fluid layer reaches its peak and/or when the oxygen is detected in the gas at the exit side, the Concentration of oxygen is held. When the concentration of oxygen at the exit side and at the entrance side becomes equal and/or when the temperature inside the layer is lowered to a temperature at a start of a stabilization operation, the layer is cooled down to room temperature and the stabilization operation is finished. Thereby, a uniform and dense film is formed and a high sigmas and a high stability against oxidation are obtained.
