Abstract
A magnetoresistive device includes a substrate and a magnetic film which is formed by alternately stacking magnetic and non-magnetic layers with each other on the substrate. The substrate is prepared to have a texture on its surface, and the magnetic film is formed on this substrate so that a texture is formed along the interface between the magnetic and non-magnetic layers. The texture can be an atomic level texture with step features dimensioned dependent upon the lattice constant, or may be an etched texture of features having desired dimensions in a specified range.
