The power-law formula is used for the analysis of the observed data from the literature. Critical exponents we determine from our analysis indicate that K2CoCl4 exhibits a weak first order transition. Coercive field EC is also analyzed using the experimental data which decreases smoothly as the temperature increases toward the transition temperature T-C. It is concluded that the theoretical model(s) with the non-zero applied electric field, can explain the ferroelectric properties of K2CoCl4 close to the phase transitions.eninfo:eu-repo/semantics/closedAccessFerroelectricityDielectric ConstantSpontaneous PolarizationCoersive FieldK2Cocl4Article5041Q4Q41521WOS:000388662900002
