Japanese Patent JPH0817248
Kind Code:
B2
Abstract:
PURPOSE:To achieve high density and improved orientation properties by adding metal fine grain powder to a pin rearray type ferromagnetic substance with a low transition temperature band. CONSTITUTION:A mixed particle between a fine grain powder consisting of a spin rearray type ferromagnetic substance 10 whose transition temperature band is lower than room temperature (approximately 25 deg.C) and a metal fine grain powder expressed by R', M', and z. (R': a rare-earth element, M': Al, Si, V, Fe, Co, and Mo, 4.4<=Z'<=5.5) is formed at room temperature within magnetic field. After that, the transition temperature band is shifted to a higher temperature side by sintering to form a temperature-sensitive magnetic body 14 where the direction of the axis of easy magnetization becomes parallel to the direction of C axis of crystal exceeding room temperature. The mixture ratio of the metal fine grain powder 12 is 0.01-0.60mol in reference to a spin rearray type ferromagnetic substance 101mol. It achieves high-concentration and improved-orientation properties.
