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. (C) 1999 Elsevier Science B.V. All righ
