Abstract

We consider the two-magnon system in a one-dimensional non-Heisenberg ferromagnet of spin s = 1 with nearest and second-nearest neighbor interactions. We demonstrate that at most two two-magnon bound states can exist in the system for λ = π and λ = 0, and at most six such states for λ = π/2.
