The influence of Cu dopant (x) and sintering temperature (Ts) on the transport properties of La2/3Ca1/3Mn1−xCuxO3 series samples prepared by Sol-Gel technique was investigated. X-ray diffraction patterns show that all the samples with different Cu dopant and sintering temperatures (Ts) are of single phase without obvious lattice distortion. Experimental results indicate that the insulator-metal transition temperature is directly related to the sintering temperature and Cu dopant x. It is interesting to observe that a proper amount of Cu dopant can substantially improve magnetoresistance effects. [ABSTRACT FROM AUTHOR] |
