WebOct 27, 2010 · Abstract. It is proposed that the photo-induced magnetic soliton in the dilute magnetic semiconductors (DSM) is introduced, by using the theoritical formula, which is on the gauge-invariant effective Lagrangian density. We have discussed the localization mechanism in the transport property of the magnetic soliton.
