摘要： PROBLEM TO BE SOLVED: To provide a magnetoresistive effect element which can exhibit a high magnetroresistive effect by means of: suppressing the roughness of interface (wall surface) with magnetic fine junction point and smoothing it; and preventing the loss of a resistance change rate caused by scattering of electrons on the wall surface in the magnetoresistive effect element which exhibits the magnetoresistive effect by an abrupt change in the magnetization at a magnetic fine junction point.
SOLUTION: The magnetoresistive effect element comprises: a laminate including a magnetization fixed layer having a magnetization direction fixed substantially in one direction, a magnetization free layer whose magnetization direction varies with an external magnetic field, and an intermediate layer provided between the magnetization fixed layer and the magnetization free layer; and a pair of electrodes electrically connected in a vertical direction of the laminate to pass a sense current through the laminate in a direction nearly vertical to the film surface of the laminate. The intermediate layer includes a compound part which covers an insulating part, a magnetic metal part, and at least part of the outer periphery of the magnetic metal part.
