Spin Polarization and Exchange Interaction in a Diluted Magnetic Qunautm Dot
The spin interaction energy of different Mn2+ ions with and without an itinerant electron is evaluated for different dot radii. Magnetization is calculated for various concentrations of Mn2+ ions with different dot sizes. Spin polaronic shifts are estimated using a mean field theory. The lowest bin...
