摘要: The possibilities of the generation of secondorder dc and secondharmonic magnetic fields excited by the magnetostatic surface wave (M SSW) and backward volume wave (MSBVW) in ferromagnetic films have been analyzed and discussed through the calculations of source terms in the equations satisfying the magnetostatic potentials. The results show that the nonlinear magnetization responses of the film to the MSSW can generate neither dc nor the secondhar monic magnetic fields. And the responses to the MSBVW will not induce the dc field, but can excite secondharmonics under some conditions. The general expressions of third order nonlinear magnetization are also derived and discussed.
