Reduction of noise, and optimization of magnetic field sensitivity and electrical properties in magnetic tunnel junction devices

摘要

Magnetic tunneling junction devices (MTJ) useful for sensing and memory applications and characterized by reduced resistance, magnetic noise, increased sensitivity, and increased magnetoresistance are disclosed herein. A method for fabrication of said MTJ is also disclosed wherein a series of materials are layered upon a substrate under controlled conditions, patterned and subjected to a period of annealing for simultaneously optimizing a plurality of performance parameters.
