Efros - Shklovskii variable range hopping (ES-VRH) conduction mechanism $[\rho = \rho_0{exp}{(T_{ES}/T)^{1/2}}]$ is observed in composites of polymer and iron carbide nanoparticle embedded in carbon relatively at high temperatures. A crossover from one ES-VRH type to another ES-VRH type is observed with different ES temperature $(T_{ES})$ and prefactor $(\rho_0)$ as temperature decreases.
