ABSTRACT:
A multichannel magnetic head has a Hall element which is disposed in a magnetic circuit which is traversed by a magnetic flux to be detected and which is used as magnetic/electric converting means. The Hall element comprises an amorphous magnetic thin film consisting of an alloy containing a rare earth element and a transition metal. To the amorphous magnetic thin film are connected a pair of current terminals and a plurality of Hall voltage terminals corresponding in number to the number of channels of the multichannel head, and the amorphous thin film is arranged in magnetic circuits of a plurality of channels.
