Abstract

A method of writing binary data comprising (i) heating a magnetic microstructure from an initial temperature to an above-ambient temperature that is not less than a transition temperature for the magnetic microstructure, which causes a phase transition interlayer of the magnetic microstructure to transition from an antiferromagnetic phase to a ferromagnetic phase; and (ii) reversing an orientation of magnetization of a magnetic storage layer of the magnetic microstructure with a magnetic field while the phase transition interlayer is in the ferromagnetic phase.
