Magnetotransport properties of GaMnAs/InGaAs superlattice structure and GaMnAs/GaAs single layers have been investigated from 4 to 300 K and magnetic fields up to 22.5 T. All these magnetic semiconductors show the so-called "paramagnetic-to-ferromagnetic phase transition''. However, in GaMnAs/InGaAs superlattice beside the Curie Wiess temperature (T-c similar to 40 K), a new phase transition is observed close to 13 K. (C) 2004 Elsevier B.V. All rights reserved.
