Abstract:
1. A magnetic device, comprising: a seed layer; a pinned layer structure disposed over the seed layer, wherein the pinned layer structure has a first portion extending to an air bearing surface; a ferromagnetic layer disposed over a second portion of the pinned layer structure adjacent to the first portion, wherein the ferromagnetic layer is recessed from the air bearing surface; an antiferromagnetic layer disposed over the ferromagnetic layer; a spacer layer disposed over at least a portion of the first portion and the second portion of the pinned layer structure, a free layer disposed over a first portion of the spacer layer; a capping layer disposed over the free layer; an insulation layer disposed over a side wall of the capping layer, a side wall of the free layer, and a second portion of the spacer layer, wherein the ferromagnetic layer is disposed over a portion of the insulation layer; and a dielectric layer disposed over the antiferromagnetic layer.
