<p>Disclosed is a multichannel magnetic head having magnetic circuits for respective channels, each positioned to traverse a magnetic flux ( phi ) to be detected, and a Hall element disposed in the magnetic circuits and used as magnetic-electric converter. The Hall element (14) is an amorphous magnetic thin film which consists essentially of an alloy containing a rare earth element (e.g. Gd) and a transition metal (e.g. Co). To the amorphous magnetic thin film (14) there are connected to a pair of current terminals (20, 22) and Hall voltage terminals (161-164). The Hall voltage terminals are provided in the same numbers as the annels or the magnetic circuits (71-74). </p> |
