1.
The difference between the magnetic moments for the samples with respective doping level can be ascribed to the variation of the competition between thermal effect and the magnetic coupling . based on the spin orientation rotation of dy sublattice as well as the antiferomagnetic coupling between dy sublattice and mn sublattice , we successfully elucidate the changes of magnetic structure in perovskite compounds s . electron spin resonance ( esr ) study on perovskite compounds on the basis of chapter 4 , we give further study on micromagneticism of dy - doping perovskite compounds la0 . 67 - xdyxsr0 . 33mno3 其中第一节简单回顾了早期对a位双稀土元素元素掺杂钙钛矿化合物的研究，早期研究较多的是替代元素的离子半径变化上，由于替代离子半径的改变，使a位平均半径变ylll化，致使公差因子改变，使mn o长、键角变化，晶格效应的作用使化合物的磁性、电性、 cmr效应发生改变。
