摘要：
Synthesis, structure and magnetic properties of Ru doped perovskite structured manganite La0.5Sr0.5MnO3 were investigated experimentally. A hydrothermal method was used for the preparation of the samples. A high-temperature annealing process was also employed to make a comparison. A slightly enhancement of the unit cell volume was observed with the increase of Ru concentration. Scanning electron microscopy shows that the materials are made up of cube-shaped particles with dimension of several micrometers. Importantly, it is found that both the Curie temperature TC and saturation moment can be reduced by Ru doping. The value of coercive field is not affected by the introduction of Ru.
