| The temperature dependencies of a spontaneous polarisation, Ps, and pyroelectric modulus, γ, at different electric field intensities were investigated for the triglycine sulphate crystals doped with the Cr3+ chromium ions. On the base of thermodynamic theory the temperature dependencies of Ps and γ at different electric field intensities were estimated. The coefficients of the expansion of the thermodynamic potential were determined. The experimental results were compared with those obtained according to the thermodynamic theory. |
