Abstract
A voltage-controlled magnetic anisotropy (VCMA) magnetic tunnel junction (MTJ) device includes a bottom electrode, a bottom CoFeB fixed layer disposed above and in electrical communication with the bottom electrode, a MgO layer disposed above the bottom CoFeB fixed layer, a top CoFeB free layer disposed above the MgO layer, a Mo capping layer disposed above the top CoFeB free layer, and a top electrode disposed above and in electrical communication with the Mo capping layer. A magnetization state of the top CoFeB free layer is switchable between an original state and an opposite state by applying a switching voltage across the MTJ device for a switching duration corresponding to a half period of a magnetic moment precession of the top CoFeB free layer.
