A simple details of the circuit with suggested capacitor and other component values will be very much appreciated. Trying to set it up for students and teach topics related to ferroelectricity. Thank you!!!
Have you tried looking in their original article: C. B. Sawyer, C. H. Tower; Rochelle salt as a dielectric; Physical Review; Vol. 35; No. 3; February 1930; pp. 269-275? Fig. 1, p. 270, provides some component values for the circuit. This article can be downloaded from the following URL: https://physlab.lums.edu.pk/images/4/43/Ref.2.pdf .
