Abstract
A magnetoresistive effect element (MR element) includes first and second magnetic layers of which relative angles formed by magnetization directions change in relation to an external magnetic field; and a spacer layer positioned between the first magnetic layer and the second magnetic layer. The first magnetic layer is positioned on a side closer than the second magnetic layer in regards to a substrate above which the magnetoresistive effect element is formed, and the spacer layer includes a main spacer layer made of gallium oxide as the primary component, and a first nonmagnetic layer positioned between the main spacer layer and the first magnetic layer and contains copper and gallium.
