Based on the theory of measurement of ferroelectric materials, the concept of phasor is used to theoretically deduce the influence of linear induction capacitance and leakage of ferroelectric thin film on the measurement of hysteresis loop. According to the characteristics of the ferroelectric thin film and the measured results, the influence of the frequency of the electrode and the test signal on the measurement is analyzed. The advantages of preparing the microelectrode for the ferroelectric thin film and appropriately increasing the frequency of the test signal are proposed during the test.
