-
In this paper, we first investigate the impurity effect ( ba2 + ) on the dielectric and phase transition properties in srtio3 within the framework of the transverse - field ising model ( tim ). then a possible coupling mechanism between the magnetism and dielectric properties in eutio3 is discussed and the magnetic influence on the frequency of the soft - phonon mode is investigated via the heisenberg model, soft - mode theory under the mean field approximation, the second quantization theory and the perturbation theory. and we proceed further investigation on eu1 - xbaxtio3 of
我們發現baxeul _ xtio3 （ o 『 x 『 0 . 2 ）的介電常數和由內察的偏置場導致的電極化除了隨雜質濃度產生相應的變化，同時在磁和介電性質的藕合作用影響下在低溫下偏離通常的量子順電體行為，在尼爾溫度附近出現異常，且磁場通過對最近鄰自旋關聯的作用來影響介電常數和電極化。 -
The dependence of the curie temperature and the critical transverse field on the long - range exponent is obtained. long - range effects on the pyroelectric coefficient and susceptibility of a ferroelectric bilayer with a ferroelectric interfacial coupling are investigated by use of the transverse ising model within the framework of mean field theory
同時還考察了長程相互作用對居里溫度和臨界橫場的影響；界面、長程相互作用及橫場對鐵電雙層膜的熱電性質和介電性質的影響在本文的第三部分我們作了較為詳細的研究。
