Yi. Mazur et al., EXCITONIC MAGNETOLUMINESCENCE ENHANCEMENT IN SEMIMAGNETIC HG1-X-YCDXMNYTE, Semiconductor science and technology, 11(9), 1996, pp. 1291-1301
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.
