The temperature dependences on the resistance in all the thin films show that in the low temperature range the width of eg band level changes the transports , but in the high temperature range the thin films forms the small polarons hopping conductivity . the phase transition induced by the current is explained by the demagnetization and lattice distortion 在高温部分,材料呈现小极化子跳跃形式输运特征;实验研究了不同偏置电流对薄膜的相变影响,表明电场可以引起材料中磁性的变化和晶格畸变,导致相变温度点向低温方向移动;材料的光致相变研究表明光子能量、光强和极化方向对输运性质有影响。
To characterize the particle size of the srce03 products , some methods used to determine the crystalline grain size and crystal lattice distortion rate of nanostructured powder based on xrd data were studied . it was found that some methods had their shortage . to rationalize the calculation , a proper treating method was recommended 为了表征所制备的纳米srceo3粉体的粒度,本论文对利用粉晶x射线衍射技术表征纳米粒于的粒度和晶格畸变的方法进行了研究,发现已有的某些方法中存在的不合理性,针对表征方法的合理化提出了自己的见解。
