Current heating of a magnetic 2DEG in HgMnTe/HgCdTe quantum wells
Abstract
Heating caused by electrons with excess kinetic energy has been investigated in a magnetic two-dimensional electron gas, M2DEG, in HgMnTe/HgCdTe(001) quantum wells. The temperature of the Mn ions, TMn, has been determined by the node positions in the beating pattern in Shubnikov-de Haas oscillations.The experimental dependence of TMn on current and therefore on electron temperature, is in excellent agreement with a rate equation model. Results with this model show that the energy transfer rate from the electrons to the Mn system is proportional to the Mn concentration.
