Abstract
A magneto-impedance element, showing a change in impedance in response to an external magnetic field when an alternating current is applied, is composed of a glassy alloy. The glassy alloy is composed of at least one base metal selected from the group consisting of Fe, Co and Ni; at least one additional metal selected from the group consisting of Zr, Nb, Ta, Hf, Mo, Ti and V; and B. The glassy alloy has a temperature region &Dgr;T,, of the supercooling liquid zone of 20° C. or more which is represented by the equation &Dgr;T,=T,−T,wherein T,is the crystallization temperature and T,is the glass transition temperature. A magnetic head, a thin film magnetic head, an azimuth sensor and an autocanceler are provided with the MI element.
