Adiabatic to non adiabatic change in conduction mechanism of Zn doped La0.67Sr0.33MnO3 perovskite

► Prepared Zn doped La0.67Sr0.33MnO3 by solid state reaction route. ► Studied the structural and electrical transport properties of the samples. ► Density of states decreases with concentration but increases with magnetic field. ► Hopping range and energy increases with dopant but decreases with magnetic field.
