Abstract

La1-xSrxMnO3 (0.1£ x £0.2) polycrystalline ceramics were prepared by the optimal sol-gel methods. Room temperature TCR and Tk of LSMO (x = 0.16) were obtained at 2.7% K-1 and 292.5 K, respectively.Mn4+ ion concentration increased by Sr doping, which was attributed to the DE and JT effects.
