  • optical spin orientation of a single Manganese Atom
    Physica Status Solidi (c), 2010
    Co-Authors: Le C Gall, R. Kolodka, L Besombes, H Boukari, J Cibert, D Ferrand, H Mariette
    Abstract:

    An optical spin orientation is achieved for a Mn Atom localized in a semiconductor quantum dot using quasiresonant excitation at zero magnetic field. Optically created spin polarized carriers generate an energy splitting of the Mn spin and enable magnetic moment orientation controlled by the photon helicity and energy. The dynamics and the magnetic field dependence of the optical pumping mechanism shows that the spin lifetime of an isolated Mn Atom at zero magnetic field is controlled by a magnetic anisotropy induced by the built-in strain in the quantum dots. Relaxation times exceeding the micro-second range are measured (© 2010 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim)

  • optical spin orientation of a single Manganese Atom in a quantum dot
    Solid State Communications, 2009
    Co-Authors: L Besombes, R. Kolodka, Le C Gall, H Boukari, J Cibert, D Ferrand, H Mariette
    Abstract:

    The magnetic state of a single magnetic Atom (Mn) embedded in an individual semiconductor quantum dot is optically probed using micro-spectroscopy. A high degree of spin polarization can be achieved for an individual Mn Atom localized in a quantum dot using quasi-resonant or fully-resonant optical excitation at zero magnetic field. Optically created spin polarized carriers generate an energy splitting of the Mn spin and enable magnetic moment orientation controlled by the photon helicity and energy. The dynamics and the magnetic field dependence of the optical pumping mechanism shows that the spin lifetime of an isolated Mn Atom at zero magnetic field is controlled by a magnetic anisotropy induced by the built-in strain in the quantum dots. The Mn spin distribution prepared by optical pumping is fully conserved for a few microseconds. This opens the way to full optical control of the spin state of an individual magnetic Atom in a solid state environment.
