Abstract:
Optically detected magnetic resonance (ODMR) was applied to reveal the
exchange interaction effects between Mn$^{2+}$ ions and confined holes in
(Cd,Mn)Te quantum wells with 2D hole gas. Two anisotropic ODMR signals with
different angular variations were found and ascribed to isolated manganese ions
and to exchange-coupled complexes consisting of manganese and holes. It is shown
that calculations on the basis of spin Hamiltonian for these systems are in
agreement with the experimental data.
