a, b Schematic illustration of pump polarization dependence of THz measurement in 2D-HMH/NiFe heterostructure as a function of the relative angle (Θ) between pump linear polarization axis with respect to the magnetic field. c, d 2D contour plot of the electric field of THz radiation along the x-direction as a function of time and polarization angle (Θ), exhibiting strong linear polarization-modulated THz intensity in both two peak groups. Panels e and f summarize the opposite changes of the polarization-dependent THz intensity in Peak 1 and Peak 2 with the switching of the magnetic field, respectively.
