Magnetotransport properties of short period GaMnAs/InGaAs superlattices

Hernandez, C. ; Terki, F. ; Viennois, R. ; Charar, S. ; Sadowski, Janusz LU and Maude, D. (2004) In Journal of Magnetism and Magnetic Materials 272. p.1429-1430
Abstract
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.
