Structure of the MTJ/FE PMN-PT magnetoelectronic hybrid devices

(A) Schematic of the MTJs on the (011)-oriented PMN-PT ferroelectric substrate. The IrMn and Au layers serve as the top and bottom electrodes for the applied E-fields across the thickness of the ferroelectric PMN-PT layer.

(B) Cross-sectional view of the oval-shaped MTJs with a layer structure of PMN-PT/Ta (50)/Ru (300)/Ta (50)/CoFe (20)/IrMn (180)/CoFe (30)/Ru (8.5)/CoFeB (30, reference layer, RL)/MgO (20, barrier layer, BL)/CoFeB (30, free layer, FL)/Ta (50)/Ru (100). The numbers refer to thicknesses in angstroms.
