| Abstract | We prepared a splicing structure by using electron beam lithography, in which Pt and Ta were spliced together as the spin source upon perpendicularly magnetized Pt/Co/Pt heterostructures. It is found that Pt and Ta can modulate both spin-orbit torque and Dzyaloshinskii-Moriya interaction on the same magnetic layer, respectively. The four-state magnetization switching is achieved with the combinations of two spliced parts, which is observed by using a magneto-optical Kerr microscope. The initial nucleation position determines the chirality. The Pt side stabilizes a right-hand Neel domain wall and the Ta side stabilizes a left-hand Neel domain wall. Our study provides a method for further increasing the storage density and studying spin-orbit torque laterally. |
