A magnetic film with 0.08 deg of large Kerr rotation angle was developed. A magnetic characteristic of the film decreased only 4 % at 150 deg C of ambient temperature. An optical probe current sensor using the magnetic film with large magnetic Kerr effect was fabricated and evaluated. The optical probe current sensor was able to measure up to 500 A (16 kA/m) and respond linearity. A measuring range of current in the sensor was 10 times as wide as that in a conventional sensor. The sensor has noise immunity, so that the optical probe current sensor will be used as the sensor for large current in the power electronics such as the electric vehicles and the factories.
