【 摘 要 】

We have discussed the dynamics of photo-induced magnetic solitons in the perovskite GdSrMnO by using quantized massive gauge fields, which are introduced theoretically in the path-integral method. For the first time, we propose the magnetic relaxation mechanism of photo-induced magnetic solitons by using the effective Hamiltonian with the p-magnetic solitons interaction and the Langevin equation.
