Possible Origins for Paramagnetic-ferromagnetic and Insulator-metal Transitions as well as Colossal Magnetoresistance in Manganites李建青,袁松柳School of Sciences,Huazhong University of Science... La2/3Ca1/3MnO3. It is argued that the common origin for insulator-metal and paramagenetic ferromagnetic-transitions as well as colossal magnetoresistance is due to the formation of ferromagnetic clusters......
. The results suggest that the high temperature LFMR effect and the applicable colossal magnetoresistance (CMR) materials could be obtained by controlling the microstructures of this class of perovskite manganites.
