(a) The definition of the angular α, β, and γ in this figure. A 7 kOe rotatable magnetic field is applied. (b) The angular ( α , β , γ ) dependence of the nonlocal voltage in Pt/YIG/Cu/Ni. The inset shows the schematic illustration of the sample structure and the measurement method. An injected current I in = + 8 mA is applied along the y axis in the Pt layer, and the nonlocal voltage V nl is measured along the y axis in the Ni layer. (b) The nonlocal voltages at α =180° in the Ni layer for Pt/YIG/Cu/Ni with injected currents I in = − 8 mA , −4 mA, 0, +4 mA, and +8 mA in the Pt layer.
