摘      要：We investigated the effect of different synthesis techniques on the structural, magnetic and magneto-transport properties of Pr0.7Sr0.3MnO3 (PSMO) samples. The samples were synthesized by three different techniques: solid state reaction, sol-gel and chemical Co-precipitation method. XRD studies confirmed the single phase formation of PSMO by all three techniques. It was also found that the magnetotransport properties of PSMO strongly depended on the synthesis techniques. A substantial decrease in the insula...
