Abstract
The temperature (T) dependencies of resistivity (rho(0)) and magnetoresista nce (MR) in the range of 100-300 K have been investigated in La0.825Sr0.175 MnO3-delta polycrystalline samples with different sintering temperatures T T-S (1300 degrees C and 1360 degrees C). Two peaks on the rho(0)(T) curve w ere found in the sample with the lower value of T-S. Inhomogeneity of the s pin configuration and multiply-connectedness of ferromagnetic phase is beli eved to give rise to anomalous behavior of resistivity below the Curie temp erature.
