Photoluminescence of cleaved Cd0.7Mn0.3Te crystals is studied at T≈1.6 K at the normal- and oblique (45º) incidence of the pumping Ar laser beam (λ=488 nm) in magnetic fields -7≤ B≤7 T in the Voigt geometry. At B=0, photoluminescence maximum is found at 2.0819 eV at normal incidence (and backward emission) whereas the oblique incidence and emission shows photoluminescence maximum intensity at 2.0536...
Photoluminescence of p-type modulation doped (Cd,Mn)Te quantum wells is studied with carrier density up to 5×10^{11} cm^{-2} at various spin splittings. This splitting can be made larger than the characteristic energies of the system thanks to the giant Zeeman effect. At small spin splitting and regardless of the carrier density, the photoluminescence exhibits a single line, which corresponds to the...
