Title: Sensor with magnetic film
Inventor: IWAKUNI HIDEJI
IPC: H01F10/00
Filed: 1990-11-30
Abstract: PURPOSE:To improve the overall residual magnetization characteristic and coercive force characteristic of both magnetic films so as to improve the reproduction output voltage of the films in a wide frequency band by constituting the films in such a way that one film can have a higher coercive force characteristic than the other film has, whereas the other film has a higher residual magnetization characteristic than the one film has. CONSTITUTION:Since each of magnetic films 3 is formed by piling up a primary magnetic film layer 3a containing a large amount of an iron oxide having a high coercive force characteristic and a secondary magnetic film layer 3b containing a large amount of iron tritetraoxide having a high residual magnetization characteristic, the overall residual magnetization characteristic of the films 3 is improved by the layers 3b having a high residual magnetization characteristic while the overall coercive force characteristic of the films 3 is improved by the layers 3a having a high coercive force characteristic. Accordingly, the reproduction output voltage of the films 3 can be improved not only in a high frequency band by the layers 3a, but also in a low frequency band by the layers 3b having a high residual magnetization characteristic. Therefore, the reproduction output voltage of the films 3 can be improved in a wide frequency range from a low frequency band to a high frequency band.
