The possibilities of the generation of the second-order dc and second-harmonic magnetic fields excited by the magnetostatic surface wave (MSSW) and backward volume wave (MSBVW) in ferromagnetic films have been analyzed and discussed through the calculations of the 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 second-harmonic magnetic fields, and the responses to the MSBVW will not induce the dc field, but could excite second-harmonics in the conditions of phase-matching and H_0/M_0 &≤ cos^2(θ/3). The general expressions of the third-order nonlinear magnetization induced by electromagnetic waves are also derived, and the contributions of the second-order magnetization are analyzed.
