Using Harmonic Analysis to Determine the Coefficients of Expansion in the Electrical Energy of a Rb2ZnCl4 Crystal from Its Polarization

详细

Values of the expansion coefficients of electrical energy W_c in a series with respect to even powers of polarization P_c are determined using the Landau–Devonshire theory by studying the repolarization dynamics of an Rb₂ZnCl₄ crystal. Experimental results obtained from the dynamics are compared to theoretical representations of the Landau–Devonshire theory that describe the dependences of W_c(P_c) in statics.
