Abstract

International audienceNonlinear ferromagnetic resonance (NFMR) at the nanoscale differs from the same phenomenon in bulk magneticsamples due to the nanosize-related discreteness of the spin wave spectrum. Because of the spectrum discreteness,the conservation laws for multiwave parametric interaction processes cannot be fulfilled exactly and become nonresonant.The presence of the nonresonant parametric processes in a strongly driven magnetic nanosystem can be detectedexperimentally as distortions on the NFMR curve caused by the nonresonant excitation of spin wave modes
