摘要
The temperature dependent energy transfer rate between hole gas and lattice has been investigated in thin MnxGa1-xAs (x=3.7% and 4.0%) films by heating the hole system with power density P-d and measuring the hole temperature T The heating experiments were carried out in temperature range of 250 mK-1.3 K and the temperature dependency of resistivity provided the hole thermometer. When the hole temperature greatly exceeds the lattice temperature we find that P-d similar to T-n, where n is in the range of 4 - 5.
