Patent ID: 8841739

Claim:
A DIOMEJ cell comprising: a magnetoelectric junction, that itself comprises: a ferromagnetic fixed layer; a ferromagnetic, magnetically anisotropic, free layer; and a dielectric layer interposed between said ferromagnetic fixed layer and ferromagnetic, magnetically anisotropic, free layer; wherein the ferromagnetic fixed layer is magnetically polarized in a first direction; wherein the ferromagnetic, magnetically anisotropic, free layer has a first easy axis that is substantially aligned with the first direction, such that the ferromagnetic, magnetically anisotropic, free layer can adopt a magnetic polarity that is either parallel with or antiparallel with the first direction; and wherein the magnetoelectric junction is configured such that when a potential difference is applied across the magnetoelectric junction, the magnetic anisotropy of the ferromagnetic, magnetically anisotropic, free layer is altered such that the relative strength of the magnetic anisotropy along a second easy axis that is orthogonal to the first easy axis, or the easy plane where there is no easy axis that is orthogonal to the first easy axis, as compared to the strength of the magnetic anisotropy along the first easy axis, is magnified or reduced for the duration of the application of the potential difference; and a diode; wherein the diode and the magnetoelectric junction are arranged in series.
