Abstract

We report the observation of tens of minor lines of the combinational spin-flip Raman scattering in a CdTe:Mn quantum well by means of the high-resolution optical spectroscopy. Classification of this manifold leads to four characteristic values of energy, that correspond to four different types of pair clusters of Mn ions: the nearest, second, third etc. neighbors. All the four energies show up in a single experiment with a very high precision, providing experimental grounds for a deeper understanding of the d-d exchange interactions in a diluted magnetic semiconductor and demonstrating the capacity of the employed method. Notably, the major nearest-neighbor exchange constant 5.22 K was found to be smaller than its established value (6.1 K). Other detected characteristic energies are as follows: 1.51 K, 1.16 K, 0.70 K.
