Thin film magnetic element with accurately controllable track width and method of manufacturing the same
A longitudinal bias layer is laminated above a free magnetic layer with a nonmagnetic layer provided therebetween so that the magnetization direction of the free magnetic layer is oriented by RKKY interaction with the longitudinal bias layer. The RKKY interaction exerts only between the longitudinal bias layer and the regions of the free magnetic layer which are located directly below both ends D of the longitudinal bias layer. Therefore, a thin film magnetic element can be provided, in which the width dimension of a recess formed in the longitudinal bias layer coincides with the magnetic track width.
