a Schematic of RuO2/MgO/RuO2 MTJ in the atomistic simulations. The red balls denote Ru atoms, the white balls denote O atoms in RuO2, and the black balls denote MgO atoms. b The switching curve of the top layer (A-layer) of RuO₂ under the influence of an external magnetic field. The inset illustrates the final state of the switching process, where the red and blue vectors represent the spin directions of Ru atoms. The inset shows that the Ru atoms in the top layer do not undergo switching under the external magnetic field. c The switching curve of the bottom layer (B-layer) of RuO₂ under the influence of an external magnetic field. The inset illustrates the final state of the switching process, where the inset shows that the Ru atoms in the bottom layer do undergo switching under the external magnetic field.
