The Effect of Hydrostatic Pressure on the Susceptibility of Rochelle Salt

Abstract

The electric susceptibility of Rochelle salt has been studied as a function of both temperature and hydrostatic pressure. Both the upper and lower critical temperatures are altered by the pressure, but the pressure coefficients for the alterations are different in the two cases. An attempt is made to correlate the experiment with statistical mechanical theory, but it is found that the theory is not sufficiently explicit to provide a quantitative explanation of the results.
