Abstract:
A magnetic cell core includes a seed region with a plurality of magnetic regions and a plurality of nonmagnetic regions thereover. The seed region provides a template that enables formation of an overlying nonmagnetic region with a microstructure that enables formation of an overlying free region with a desired crystal structure. The free region is disposed between two nonmagnetic regions, which may both be configured to induce surface/interface magnetic anisotropy. The structure is therefore configured to have a high magnetic anisotropy strength, a high energy barrier ratio, high tunnel magnetoresistance, a low programming current, low cell-to-cell electrical resistance variation, and low cell-to-cell variation in magnetic properties. Methods of fabrication, memory arrays, memory systems, and electronic systems are also disclosed.

Claim (Index 11):
A semiconductor device, comprising:\n at least one magnetic structure over a lower electrode, the at least one magnetic structure comprising:\n a nonmagnetic oxide region between a seed region and a free region, the seed region and the free region each comprising cobalt (Co) and iron (Fe); and \n another nonmagnetic oxide region between the free region and a fixed region, \n wherein no oxide material is between the seed region and the lower electrode.
