Abstract
A MR head employs a biasing soft magnetic film of a FeXN-based alloy which undergoes no change in the direction of its axis of easy magnetization even when subject to heat treatment. The MR head has an anisotropic magnetic field size of 10 Oe or greater, and electrical resistance p of 70 .mu..OMEGA.cm or greater, and a saturation flux density Bs of 1 T or greater. The direction of the axis of easy magnetization of the biasing soft magnetic film is oriented perpendicular to the direction of sense current, and the direction of the axis of easy magnetization of the MR film is oriented parallel to the sense current direction.
