(1-x)La_0.70Sr_0.30MnO₃ (LSMO) – (x)ErMnO₃ (EMO) (x = 0.00, 0.10, 0.20, and 0.30) ceramics were synthesized by chemical route. The structure characterization of all the samples was carried out at room temperature. The LSMO has rhombohedral symmetry with space group R-3C and EMO has hexagonal symmetry with space group P63/mcm. The temperature-dependent resistivity behavior of pure and composite samples has shown metal-insulator (MI) transition. The peak resistivity ρ_max increases with decrease in MI transition temperature. Percentage magneto-resistance (MR) variation of LSMO-EMO (x = 0.10, 0.20, and 0.30) with temperature has also been studied. The result of ln (ρ) vs. Tⁿ shows that conduction occurs due to variable range hopping (VRH) of electrons for x = 0.20 and 0.30. % MR data has been statically analyzed which shows the normal distribution.

 通过化学路线合成了（1- x）La _0.70 Sr _0.30 MnO ₃（LSMO）–（x）ErMnO ₃（EMO）（x = 0.00、0.10、0.20和0.30）陶瓷。所有样品的结构表征均在室温下进行。LSMO具有R-3C空间群的菱形对称性，而EMO具有P63 / mcm空间群的六角形对称性。纯样品和复合样品的随温度变化的电阻率行为显示出金属-绝缘体（MI）的转变。峰电阻率ρ_最大增加与MI转变温度降低。LSMO-EMO（x的百分比磁阻（MR）变化 （0.10、0.20和0.30）随温度的变化也已被研究。ln（ρ）对T ^n的结果表明，由于x  = 0.20和0.30时电子的可变范围跳变（VRH），发生了传导。％MR数据已被静态分析，显示出正态分布。
