Recently, magnetic thin film devices using magneto resistance (MR) effect are useful for the hard disk drive heads and the magnetic sensors. Therefore magneto resistance effect films have been widely studied, and a rapid progress is being made in this field. We had proposed a new thin-film device. The new proposed thin film device is a magnetic thin film power sensor. The output signal of magnetic thin film power sensor is a dc voltage. In this paper, we report high frequency electric power measurement in the range of MHz frequency with magnetic thin film power sensor.
