| 中文摘要 | La1 -xTexMnO3(x=0 0 4 ,0 1)是一种具有钙钛矿结构的电子掺杂型锰氧化物 .实验结果表明 :在这种锰氧化物中同时存在庞磁阻 (CMR)效应和低场磁电阻 (LFMR)效应 .在整个实验温度范围 ( 5— 30 0K) ,LFMR随温度升高而发生了如下变化 :出现—消失—出现 ,在LFMR消失的温区又恰好能观察到明显的CMR .对其原因给予了解释 .; The colossal magnetoresistance (CMR) effect and the low-field magnetoresistance (LFMR) of the electron-doped manganites La 1 -x Te x MnO 3 ( x =0.04, 0.1) have been observed. The experimental results showed that LFMR of the samples varied with the increase of temperature from 5 to 300 K as follows: appearing-disappearing-appearing again. Furthermore,the samples exhibited large CMR in the temperature regime where the LFMR disappear. These related results have been analyzed.; 国家基础研究重大项目基金 (批准号 :G19980 614 12 ); 中国博士后基金资助的课题~~ |
