| Research Abstract |
We have investigated TMR and related properties of the metal-insulator nano-granular TMR films used for GIGS which is a next-generation highly efficient power-saving magnetic sensor by examining film composition, production conditions, and film structure in detail. As a result, 1) FeCo-(Si)-AlF films, these are new composition films, have good heat resistance of TMR. 2) TMR of the films prepared on the heating substrate shows good heat resistance, and has good sensitivity in a small magnetic field. 3) The structure of the films which contain a little Si doesn't change by heating. It is the reason of good heat resistance of TMR.
