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 16):
A method of forming a semiconductor device comprising a magnetic structure, the method comprising:\n forming a precursor structure, comprising:\n forming a seed material over a conductive material of a lower electrode, the seed material exhibiting an amorphous state; \n forming a lower nonmagnetic material directly over the seed material while the seed material exhibits the amorphous state; \n forming a magnetic material exhibiting a switchable vertical magnetic orientation over the lower nonmagnetic material, the magnetic material having the same chemical elements as the seed material; and \n forming another nonmagnetic material over the magnetic material; \n annealing the precursor structure to crystallize at least the magnetic material; and after the annealing and before patterning the precursor structure to form the magnetic structure of the semiconductor device, forming another magnetic material over the another nonmagnetic material, the another magnetic material exhibiting a fixed vertical magnetic orientation.
