The structure and magnetic properties of the Eu1-xSrxMnO3 (ESMO x=0—1) system have been systematically studied. The results indicate that the substitution of Sr for Eu can greatly change the magnetic properties of antiferromagnetic EuMnO3 matrix. In the case of high doping compounds (Eu0.4Sr0.6MnO3 and Eu0.3Sr0.7MnO3), the abnormal magnetic and electrical properties result from the competition between their being ferromagnetic and antiferromagnetic. At low temperature, the conducting behavior of the Eu0.4Sr0.6MnO3 and Eu0.3Sr0.7MnO3 are well fitted by the Mott variable range hopping (VRH) model.
