✦ Synopsis


We have measured resistivity, magnetization and magnetoresistance in polycrystalline La0.7_xPr, Sr0,3Mn0s with fixed carrier concentration. With decreasing the average ionic radius of the La site ( rA), we found a decrease in T,, an increase in resistivity at T,, and an increase in the magnitude of the magnetoresistance. The samples show a metal-insulator transition in the high-temperature paramagnetic phase with the variation of (~4). These results demonstrate the close relationship between (rA) and the band structure.
