We compare the results for the related to the shear strain ε4 physical characteristics of Rochelle salt obtained within the recently developed modified two-sublattice Mitsui model that takes into account the strain ε4 and the diagonal components of the strain tensor ε1, ε2, ε3 with the results of the previous modification of the Mitsui model with the strain ε4 only. Within the framework of the model with the diagonal (thermal expansion) strains, we also reexamine the effects of the longitudinal electric field E1 on the dielectric properties of Rochelle salt.

Key words: Rochelle salt, thermal expansion, Mitsui model, strains, bias field
