• Sr-doped manganites
• spin-glass
• ferromagnetic cluster

The magnetic properties of Eu1-xSrxMnO3 (x = 0.4, 0.5, 0.6, 0.7) are systematically studied. Nuclear magnetic resonance, magnetization and electrical transport measurements are carried out, and the results indicate that the substitution of Sr for Eu could produce ferromagnetic phase in antiferromagnetic EuSrMnO3 matrix. The competition between ferromagnetic and antiferromagnetic phases induces the spin-glass behavior. In addition, the magnetic properties of Eu0.4Sr0.6MnO3 and Eu0.3Sr0.7MnO3 show more complex features at low temperatures, resulting mainly from the appearance of ferromagnetic clusters and the existence of disordered structure.
