| titleOfInvention | Soft magnetic thin film and magnetic head using such thin film |
| abstract | PURPOSE: To obtain a soft magnetic thin film having high saturation magnetic flux density and having both high durability and high permeability by laminating layers of iron carbide and iron alternately. n CONSTITUTION: Layers of iron 12 and layers of iron carbide 11 having a concentration of C in a range corresponding to positive magnetostrictive constants are laminated alternately. According to such an arrangement, even if carbon is incorporated in the iron carbide layers 11 in an amount enough to present sufficient durability at the sacrifice of saturation magnetic flux thereof, the presence of the pure iron layers 12 ensures sufficient saturation magnetic flux and instability of the pure iron layers 12 can be compensated by the adjacent iron carbide layers 11. Further, the negative magnetostriction of the pure iron layers 12 and the positive magnetostriction of the iron carbide layers 11 are cancelled each other, whereby the soft magnetic thin film thus obtained is allowed to have sufficiently high permeability also. Accordingly to the invention, consequently, the soft magnetic thin film having high saturation magnetic flux density is allowed to have both high durability and high permeability. n COPYRIGHT: (C)1990,JPO&Japio |
