  In this work we constructed a two-dimensional numerical model for calculation
of the stripline ferromagnetic resonance (FMR) response of metallic
ferromagnetic films. We also conducted numerical calculations by using this
software. The calculations demonstrated that the eddy current contribution to
the FMR response decreases with a decrease in the stripline width. The most
important manifestations of the conductivity (eddy current) effect are
excitation of the higher-order standing spin waves across the film thickness in
the materials for which the standing spin wave peaks would be absent in cavity
FMR measurements and strong dependence of the off-resonance series conductance
of the stripline on the stripline width. Whereas the contribution of the eddy
currents to the stripline FMR response can be very significant, because wide
striplines (100nm+) are conventionally used for the FMR measurements, it is
negligible in the case of excitation of spin waves, just because very narrow
stripline transducers (0.5-5micron wide) are required in order to excite spin
waves in metallic ferromagnetic films in a noticeable frequency/applied field
range.
