Abstract
An MRAM bit () includes a free magnetic region (), a fixed magnetic region () comprising an antiferromagnetic material, and a tunneling barrier () comprising a dielectric layer positioned between the free magnetic region () and the fixed magnetic region (). The MRAM bit () avoids a pinning layer by comprising a fixed magnetic region exhibiting a well-defined high Husing a combination of high H(uniaxial anisotropy), high H(saturation field), and ideal soft magnetic properties exhibiting well-defined easy and hard axes.
