Abstract
AbstractThe magnetic state of a single magnetic ion (Mn2+) embedded in an individual quantum dot is optically probed using micro‐spectroscopy. The fine structure of a confined exciton in the exchange field of the single Mn2+ ion is analyzed in detail. At zero magnetic field, the exciton–Mn exchange coupling lifts the degeneracy of the six Mn spin projections. Under magnetic field, the electron–Mn interaction induces a mixing of the bright and dark exciton states. Magneto‐optic measurements reveals that the polarisation of the Mn2+ spin distribution is controlled by the magnetic field and an effective manganese temperature depending on both the lattice temperature and the density of photo‐created carriers.
