摘要
Study of the effect of an external electric field on the dielectric constant in the paraelectric phase of ferroelectric glycine phosphite crystals has been performed. The dielectric constant behavior under the bias external field has been analyzed in the framework of Landau theory. It is shown that the ferroelectric phase transition is of the first order very close to a tricritical point and the calculated value of the thermal hysteresis is DeltaT congruent to 0.1 K.
