ABSTRACT:
A structure has a substrate and a layer containing a magnetic material dispersed in a nonmagnetic material, the magnetic material being comprised of first crystal particles having an easy magnetization axis crytsllographically oriented in the direction of the normal line of the substrate and forming columns perpendicular to the substrate and second crystal particles having a crystallographic orientation in a direction different from the direction of the crystallographic orientation in the first crystal particles, and the ratio of the second crystal particles to the entire crystal particles in the columns ranging from 10% to 50% by weight.
