Niobium-modified lead zirconate stannate titanate antiferroelectric thin films with the chemical composition of $(Pb_0_._9_9Nb_0_._0_2)(Zr_0_._5_7Sn_0_._3_8Ti_0_._0_5)_0_._9_8O_3$ were deposited by pulsed excimer laser ablation technique on Pt-coated Si substrates. Field-induced phase transition from antiferroelectric to ferroelectric properties was studied at different fields as a function of temperature. The field forced ferroelectric phase transition was elucidated by the presence of double-polarization hysteresis and double-butterfly characteristics from polarization versus applied electric field and capacitance and voltage measurements, respectively. The measured forward and reverse switching fields were 25 kV/cm and 77 kV/cm, respectively. The measured dielectric constant and dissipation factor were 540 and 0.001 at 100 kHz, respectively, at room temperature.
