Abstract

In this work, we measured the longitudinal (Formula presented) and transverse (Formula presented) resistivities as a function of the current density in the flux-flow regime in (Formula presented) superlattices. According to these measurements, the Hall electric field is a nonlinear function of the current density in the vicinity of the local minimum of negative Hall coefficient. Also, the Hall resistivity is independent of (Formula presented) in the low current density. Furthermore, the (Formula presented) and (Formula presented) are found to obey the power law (Formula presented) with (Formula presented) over a wide current densities and temperatures. Above results are discussed in terms of the existing theories.
