Abstract
The electrical and magnetic transport properties of the La0.67âxEuxCa0.33MnO3 system exhibit lowering of insulator to metal and paramagnetic to ferromagnetic transition temperature (TC) with the increase of Eu concentration in addition to possessing CMR property. The temperature variation of electrical resistivity and magnetic susceptibility for x=0.21 is found to have two distinct regions in the paramagnetic state for T>TP; one with the localization of lattice polaron in the high-temperature region (T>1.5TP) satisfying the dynamics of variable range hopping (VRH) model and the other being the combination of the spin and lattice polarons in the region TP
