Abstract
The diffuseness of ferroelectric (FE) and antiferroelectric (AFE) phase transitions (PTs) in FE–AFE solid solutions of the K1–x(NH4)xH2PO4 type is discussed. A distinct correlation between the PT diffuseness parameter and the width of a PT temperature hysteresis is found. It is shown that these parameters of FE compositions are largely determined by the electrostatic interaction of random-field defects with interphase and domain boundaries.
