Abstract: With a view to investigate the magneto-structural properties and influence of annealing on magnetoresistance of strontium-doped lanthanum manganite, samples of La1-xSrxMnO3 were prepared and their magneto-transport properties have been investigated in this article. Magnetoresistance is enhanced from 6% to about 94% at room temperature due to annealing. Resistivity and Seebeck coefficient were investigated over the temperature range 83 = T = 313 K. The quasi-static magnetization was investigated in the temperature range of 5-400 K under effect of a magnetic field of 100 Oe in both moods of field cooling presence besides the zero field cooling. The measurements of magnetization showed Curie transition from ferromagnetic behavior to paramagnetic one. The Curie transition values increased with increasing the strontium content suggesting that the transfer integral between two Mn sites would be enhanced due to the substitution of smaller La ions (117.2 pm) by greater Sr ions (132 pm). Various parameters were calculated from the application of variable range hopping and single polaron hopping models. Both models were utilized to investigate the effect of Sr on the conduction behavior. The behavior of thermopower with temperature was demonstrated on the basis scatterings of phonon-and magnon-.
