摘要：

Three-dimensional solitons are predicted in a Heisenberg ferromagnet due to the leading (three-magnon) nonlinear contribution of the dipole-dipole interaction. A quantum description of the nonlinear problem is given using Glauber's coherent-state representation so that the magnetic soliton is viewed as a coherent superposition of linear magnons. © 1979 The American Physical Society.
