Abstract
Curie temperature is determined, by investigating the variation of order - parameter < s(Z) > with temperature by using Bose Green's function method i ntroducing the undetermined constants and modified model Hamiltonian propos ed by Blinc and Jeks. The contribution of four-spin interaction to the Hami ltonians in KDP and DKDP is of the same order.
