A magnetic tunnel junction cell having a free layer, a ferromagnetic
pinned layer, and a barrier layer therebetween. The free layer has a
central ferromagnetic portion and a stabilizing portion radially
proximate the central ferromagnetic portion. The construction can be used
for both in-plane magnetic memory cells where the magnetization
orientation of the magnetic layer is in the stack film plane and
out-of-plane magnetic memory cells where the magnetization orientation of
the magnetic layer is out of the stack film plane, e.g., perpendicular to
the stack plane.
