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。
