摘要：

We have identified an integrable model of the inhomogeneous radially symmetric weak Heisenberg ferromagnet in arbitrary n dimensions with Dzialoshinski-Moriya antisymmetric spin coupling. The elementary spin excitations of the magnet are found to be governed by soliton modes under small-angle oscillation of the antisymmetric spin coupling.
