摘要：
The magnetic and magnetoresistance properties of Lao(0.825)Sr(0.175)MnO(3) powder compact prepared by the mechanical alloying method and high temperature high pressure treatment have been investigated. Analysis by means of x-ray diffraction and scanning electron microscopy show that the La0.825Sr0.175MnO3 powder has an average grain size of 100 nm and has been partly non-crystallized by mechanical alloying. Compared with the crystal and general nanogranular samples of the same material. the powder compact is considerably different in both magnetic and magnetoresistance properties.
