Abstract

A novel thin film wattmeter based the magneto resistance effect is proposed. The new magnetic thin film wattmeter has a three-layered structure (conductor film-insulation film-magnetic film). It is reported that the electric power consumption in the load could be drawn from the voltage across the magnetic film along the current. Furthermore it is reported that a circle shaped magnetic thin film wattmeter shows the highest sensitivity by the results of computer simulation and the characteristic of the prototype sample. It is reported that the magnetic thin film wattmeter using the magnetic thin film was very useful as the embedded wattmeter into various electronic devices.
