| 1 | 多晶La_(0.49)Sr_(0.51)(Mn_(1-x)Nb_x)O_3的电输运特性研究显示文摘测量了B位掺杂的钙钛矿结构锰氧化物La0 49Sr0 51(Mn1-xNbx)O3(x=0,0 05,0 15和0 25)的电阻率和磁化强度的温度特性.实验结果表明,当Nb5+部分替代B位的Mn4+离子时,电阻率-温度特性由原来单一的半导体型转变成了高温时的半导体(绝缘体)型和低温时的类金属型.随Nb掺杂量增大,电阻率迅速升高3~5个数量级,半导体(绝缘体)-类金属转变温度降低.在掺杂Nb的样品中,只观察到顺磁-铁磁转变,而未观察到铁磁-反铁磁转变.上述实验结果的一种可能解释是掺杂改变了磁有序时电子自旋的排列和空间取向,从而改变载流子被自旋热涨落的散射作用和载流子转移的随机性. | 柳文军 舒启清 马晓翠 杜建设 李逢明 Troyanchuk I.O | 2004 | 深圳大学学报(理工版)2004，21，4： | 3 |
| 2 | 多晶La_(0.49)Sr_(0.51)(Mn_(1-x)Nb_x)O_3的磁电阻研究显示文摘采用四探针法测量多晶La0.49Sr0.51(Mn1-xNbx)O3(x=0,0.05,0.15和0.25)在磁场下的电阻率温度曲线.实验结果显示:①在0.45T磁场下,对于x=0和x=0.25的样品,几乎观察不到磁电阻(Magnetoresistance,MR)效应,而对于x=0.05和x=0.15的样品,磁电阻效应较明显.这种差异可能与样品中铁磁相是否占主导作用有关;②比较x=0.05和x=0.15这两种样品的MR机制,前者可能与载流子在弱连接晶界上的自旋相关散射有关,且其主要是非本征的;而后者主要是本征的. | 柳文军 朱德亮 舒启清 马晓翠 Troyanchuk I O | 2005 | 深圳大学学报(理工版)2005，22，4： | 2 |
