Abstract
A magnetic field sensor is disclosed with which the direction of a magnetic field can be determined by using the planar Hall effect. An active layer of the sensor is made of a ferromagnetic amorphous metal which is magnetically isotropic. Thus, the magnetization in the active layer always has the direction of an external magnetic field. The developed planar Hall voltage is a measure of the direction of the magnetic field.
