WebMoreover, we demonstrate spin-orbit torque driven magnetization switching using a MgO/CoFeB/α-W heterostructure. Our findings suggest that the conductive and high spin Hall conductivity α-W can be a potential candidate for future low power consumption spin-orbit torque memory applications. 收回 WebMar 9, 2024 · Conclusion. In summary, magnetoresistance and Hall resistivity characteristics of WTe 2 thin flakes have been studied. It is found that the magnetoresistance does not saturate at 8 T with a small MR. By fitting experimental data to a two-band model, we attribute the small MR to the low carrier mobility.
