Due to the inhomogeneous nature of multilayered structures, the measured conductivities for currents parallel and perpendicular to the layers are different, even if the local conductivity is isotropic. The perpendicular conductivity is derived and compared to the parallel conductivity which has been calculated previously. When our formalism is applied to Fe/Cr superlattices, interesting features of the magnetoresistance are found that can be verified by experiments.
