Abstract
Magnetic anisotropies in quantum dots (QDs) doped with magnetic ions are discussed in terms of two frameworks: anisotropic factors and magnetocrystalline anisotropy energy. It is shown that even a simple model of zinc-blende -doped QDs displays a rich diagram of magnetic anisotropies in the QD parameter space. Tuning the confinement allows us to control magnetic easy axes in QDs in ways not available for the better-studied bulk dilute magnetic semiconductors.
