Abstract
A granule-type magnetoresistive material is used to form a MR component, which is equipped in a magnetic head, or the like. When placing the magnetoresistive material in the external magnetic field, the electric resistance is altered responsive to a variation of the external magnetic field. In order to increase a magnetic-field sensitivity, the magnetoresistive material is composed of an alloy whose atomic composition is expressed by a chemical formula of (Co.sub.1-x Fe.sub.x).sub.y Ag.sub.1-y, where 0.45.ltoreq.x.ltoreq.0.55 and 0.24.ltoreq.y.ltoreq.0.35; or another chemical formula of (Co.sub.1-x Fe.sub.x).sub.y (Ag.sub.1-z Cu.sub.z).sub.1-y, where 0.45.ltoreq.x.ltoreq.0.55, 0.24.ltoreq.y.ltoreq.0.35 and z.ltoreq.0.14.
