文摘
The critical scaling behavior of ferroelectric transition in displacive-type organic ferroelectrics is investigated by Green’s function theory. The order of ferroelectric transition and universality are clarified by scaling laws. The scaling equations of hypothesis are proposed to verify the self-consistency and reliability of the critical exponents. A universal curve of electric entropy change −ΔS−ΔS is constructed with rescaling temperature and electric field.
