Abstract
Quaternary Hg1-x-yCdxMnyTe (x = 0.31-0.38, y = 0.008-0.02) crystals gr own by the travelling heater method were investigated by means of magn etoluminescence over a wide temperature (5 K < T < 100 K) and magnetic field (0 T less than or equal to B less than or equal to 7 T) range. The observed non-monotonic evolution of the photoluminescence spectra with temperature and magnetic field is interpreted in terms of exciton localization in alloy fluctuations and exchange interaction between t he free carriers and the localized spins of the 3d electrons in the ma gnetic ions. From that new arguments are drawn with respect to a struc tural improvement of ternary Hg1-xCdxTe by doping with manganese ions.
