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 在高溫部分,材料呈現(xiàn)小極化子跳躍形式輸運(yùn)特征;實(shí)驗(yàn)研究了不同偏置電流對(duì)薄膜的相變影響,表明電場(chǎng)可以引起材料中磁性的變化和晶格畸變,導(dǎo)致相變溫度點(diǎn)向低溫方向移動(dòng);材料的光致相變研究表明光子能量、光強(qiáng)和極化方向?qū)斶\(yùn)性質(zhì)有影響。
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 為了表征所制備的納米srceo3粉體的粒度,本論文對(duì)利用粉晶x射線衍射技術(shù)表征納米粒于的粒度和晶格畸變的方法進(jìn)行了研究,發(fā)現(xiàn)已有的某些方法中存在的不合理性,針對(duì)表征方法的合理化提出了自己的見解。
