Patent ID: 6888706

Claim:
A magnetic sensing element comprising a gap layer formed on a substrate; at least an antiferromagnetic layer, a pinned magnetic layer, a nonmagnetic conductive layer and a free magnetic layer constituting a trapezoid-shaped resistive multilayer laminated on a deposition surface of the gap layer; and a bias underlayer and a bias layer laminated in each side area at an inclined face side continuously formed on each side face of the trapezoid-shaped resistive multilayer from the bottom in this order, wherein the bias underlayer comprising a bcc crystal structure is formed at a level halfway of an elevation of an inclined face of the resistive multilayer with a preferential orientation of at least one of a [211] face and [200] face in a direction perpendicular to the layer surface, and wherein an entire surface of lower face of the bias layer is in contact with the bias underlayer, the bias layer being formed with an elevation at a level of the free magnetic layer on the bias underlayer.
