Generalized Holstein-Primakoff transformations for the diagonalization of quadratic terms of magnetic Hamiltonian function and explicit expressions for three- and four-magnon coefficients are derived. It is shown that antisymmetric magnetic interactions can result in frequency nonreciprocity of spin waves and affect nonlinear spin-wave processes, but do not affect ellipticity of magnetization precession. The amplitude dependence of spin wave nonreciprocity in ferromagnetic films with interfacial Dzyaloshinskii-Moriya interaction is demonstrated.  Product Description popup.authors popup.nrat_date 2020-04-02 Close
