摘要
用固相合成法合成了（Ｌａｌ－ｘＳｒｘ）（１－ｙ）ＭｎＯ３（ｘ—０～５，ｙ＝０～０．１）单纯相化合物·在空气中用直流四探针法测定了各组成的电导率．测试温度范围为１００～９５０℃．其中（Ｌａ（０．７）Ｓｒ（０．３））（０．９５）ＭｎＯ３具有最大的电导率．讨论了Ｌａ（Ｓｒ）ＭｎＯ３的电导机理．
La(1-x)Srx)(1-y)MnO3 (x=0￣5 , y=0￣0. 1 ) have been prepared by solid reaction. The electronic conductivities of La(Sr)MnO3 were carried out by a four probe method in air. (La(0.7)Sr(0.3))(0.95)MnO3showed the highest conductivity. The transport processes of La(Sr)MnO3 have been discussed.
