Figure 4: The measured voltage as a function of the magnetic field angle.

(a) Magnetic field dependence of the voltage measured at 1.7 K for θ_H=0°, 63°, 76°, 83° and 86.5°, respectively. Inset: the schematic illustration of the coordinate system for magnetic field angle. (b,c) The resonance magnetic field and half-line width as a function of θ_H.
