We report the results of transport measurements on HgTe/CdTe superlattices, performed in the temperature range 4.2–300 K and, in magnetic fields up to 8 T. A different behaviour is observed depending on the lattice spacing and the period of the superlattice. In one sample, a reversal of the sign of the Hall voltage occurs at about 4 T, while in the other one, the weak‐field Hall voltage changes its sign with increasing temperature. The angular dependence of the transverse magnetoresistance essentially follows the two‐dimensional behaviour, but a residual resistance persists when the magnetic field is parallel to the plane of the superlattice.
