Abstract
The axial fine structure with strong positive zero-field splitting
for Mn2+ ions in CdMnSe/ZnSe quantum dots caused by their low
dimensionality was revealed. Magnetic resonance was measured as a variation
of photoluminescence intensity. In spite of isotropic g factor of Mn2+
ions, the anisotropic behavior of the center of gravity of the resonance has
been observed because of the high Boltzmann factor at 35 GHz and 2 K.
