Instrument for measuring the switching transition in ferroelectric thin films

A description is given of the construction and operating principles of an instrument for investigation of the process of polarization reversing in ferroelectric thin films in an electric field arising from rectangular impulses. The system constructed enables investigation of changes of polarization as a function of intensity of electric field in a wide range of time intervals by means of an integrating system, and investigation of the time-course of polarization reversing as a function of intensity of electric field by means of a differentiating system.
