摘要
用溶胶凝胶方法制备了一系列的（Ｌａ１－ ｘＰｒｘ）２／３Ｓｒ１／３ ＭｎＯ３ 多晶样品，研究了其电磁性能及磁致伸缩效应，发现样品低温下的磁致伸缩主要以线伸缩为主，且在低场下达到饱和，在Ｐｒ 含量为０－３ 时达到最大值，约为－ ９０ ×１０ － ６ ．随Ｐｒ 掺杂含量的逐渐减小，磁致伸缩的饱和场也逐渐减小．
A series of bulk (La 1-x Pr\- x ) 2/3 Sr\-\{1/3\}MnO\-3 polycrystalline samples were prepared by sol\|gel technique and the electrical,magnetic properties and magnetostriction effect were studied.At low temperatures,the magnetostriction was mainly about linear magnetostriction and saturated at low magnetic field,and the saturation field decreased with decreasing Pr content.At x =0.3,we found a maximum value of -90×10 -6 .
