Abstract:
1. A magneto-resistive effect (MR) element, comprising: first and second magnetic layers in which a relative angle formed by magnetization directions changes in response to an external magnetic field; and a spacer layer positioned between the first magnetic layer and the second magnetic layer, wherein the first magnetic layer is positioned closer to a substrate above which the MR element is formed than the second magnetic layer; and the spacer layer includes a copper layer, a metal intermediate layer and a main spacer layer composed of gallium oxide as a primary component, the copper layer and the metal intermediate layer are positioned between the main spacer layer and the first magnetic layer, the metal intermediate layer is positioned between the copper layer and the main spacer layer, and the metal intermediate layer is composed of at least one member selected from a group consisting of one of magnesium and at least partially oxidized magnesium, as a primary component.
