Abstract
Magnetoresistive properties of La1-xSrxMnO3-delta (x = 0. 15-0.30) polycrys talline samples sintered at different temperatures T-S have been investigat ed. The results suggest that the increase in T-S gives rise not only to gro wing the averaged grain size but also to inducing additional defects, the l atter exerting minor influence at low temperatures but governing the magnet oresistance near Curie temperature.
