| 4 | Description | Abstract | Curie temperature is determined by investigating the variation of order-parameter < Szq > with temperature. The model Hamiltonian proposed by Blinc and Zeks has been modified by considering the lattice anharmonicities up to fourth order. The correlations appearing in the dynamical equation have been evaluated using double-time thermal retarded Green`s function and Dyson`s equation. The expressions for shift, width, renormalized soft mode frequency, Curie temperature, the expectation value of the proton collective mode components at site q (< Szq >,< Sxq >) and have been derived and discussed in KDP - type crystals. By fitting model values of physical quantities, the temperature dependence of < Szq > and < Sxq > for different value of four-body coupling have been calculated. The theoretical results are found in good agreement with the experimental results. |
