- W2350382502 abstract "A series of polycrystal bulk low Cu doping samples of La0.7Ca0.3Mn1-xCuxO3(x=0%,1%,2%,3%,4%,5%) have been prepared by Sol-Gel process.The temperature dependences of resistance of all the samples were measured from 77 K up to 350 K.The measurement results indicated that obvious peaks existed in the resistivity-temperature curves.Basing on nonadiabatic small polaron hopping model,we used the function of ρ=ρ0Texp(E/kT) to fit the ρ-T curves.The fitting results showed that the resistivity peaks corresponded to the transition of the phase from mater to insulator(M-I).Under this condition,using function of ρ=ρ0Texp(E/kT) deduced from nonadiabatic small polaron hopping model,we fitted the resistivity of all the samples in high temperature region(the temperature region higher than transition temperature of the phase),and the conductance activation energies of all the samples were gained respectively.The fitting results indicated that the doping of Cu ion influenced the activation energies obviously,activation energies increased gradually with the increasing of substitution contents." @default.
