Spintronic THz emitters have attracted attention due to their simple device structures and high controllability of THz signals. In this study, using a nonmagnetic/ferromagnetic bilayer on a ferroelectric LiNbO₃, we report tuning effects of THz signals induced by its spontaneous ferroelectric polarization.
