“…1(b) are anisotropic. They are similar to those observed in (CdMn)Te QW with 2DHG [5] and consist of two lines. With the increasing angle θ between the magnetic field direction and the [001] growth axis the narrow line slightly shifts from high fields corresponding to g<2 for θ=0 to lower fields (g>2) while the anisotropy of the broad line is much larger and shows the opposite behavior.…”

In (CdMn)Te QWs without 2DHG no such broad line was found [5,9]. The observed anisotropy suggests that localized holes may be involved in the paramagnetic center.…”

Optically detected magnetic resonance study of (CdMn)Te/(CdMg)Te quantum wells allowed to reveal the formation of exchange‐coupled complexes consisting of Mn ions and localized holes in quantum wells with excess hole concentration and the directional electron tunneling towards wider wells in multiple quantum well structures. The existence of a distribution of Mn‐hole complexes that differ in a number of Mn ions interacting with a localized hole is justified. In colloidal cobalt doped ZnO nanocrystals, several nm in diameter, the interaction between the magnetic ions and the shallow donor electron in the confined system of ZnO quantum dots has been revealed. Direct evidence of interaction of Co ions with the interstitial Li shallow donor in the ZnO nanocrystal core and hyperfine coupling with 1H in the quantum dot shell have been demonstrated.
