Patent ID: 8158190

Claim:
A method of producing a magnetic memory device having one or more free magnetic layers comprises the steps of: tuning the saturation magnetization of the one or more free magnetic layers to have a saturation magnetization of less than or equal to about 600 electromagnetic units per cubic centimeter, wherein tuning the saturation magnetization of the one or more free magnetic layers to have a saturation magnetization of less than or equal to about 600 electromagnetic units per cubic centimeter facilitates maintaining a uniformity of switching, wherein maintaining a uniformity of switching comprises configuring the device such that a ratio of mean switching field associated with an array of non-interacting magnetic memory devices and a standard deviation of the switching field is greater than or equal to about 20; and adding one or more moment-reducing elements to the one or more free magnetic layers to reduce a magnetic moment of the device, the one or more moment-reducing elements consisting of germanium, boron, vanadium, molybdenum, osmium or a combination comprising at least one of the foregoing moment-reducing elements.
