A decrease in the magnetization of the film due to an increase in its temperature can be used to account for the effect of light on wave propagation. The stepwise transformation of the trajectories of propagating waves that is synchronous with the time parameters of the femtosecond pulse is revealed. The transformation of trajectories is interpreted using the method of isofrequency curves and the Hamilton–Auld method.</p></abstract><trans-abstract xml:lang="ru"><p id="idm45181322991600">Рассмотрена трансформация траекторий поверхностных магнитостатических волн, распространяющихся в ферритовой пленке, намагниченной линейно неоднородным полем, вызванная воздействием мощного импульса света от фемтосекундного лазера. В качестве механизма действия света на распространение волн отмечено уменьшение намагниченности пленки за счет повышения ее температуры. Выявлен ступенчатый характер трансформации траекторий распространяющихся волн, синхронный с временными параметрами фемтосекундного импульса. Трансформация траекторий интерпретирована на основе методов изочастотных кривых и Гамильтона–Аулда.</p></trans-abstract><kwd-group xml:lang="en"><kwd>surface magnetostatic waves</kwd><kwd>femtosecond laser pulse</kwd><kwd>method of isofrequency curves</kwd><kwd>Hamilton–Auld method</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Adam J.D., Davis L.E., Dionne G.F. et al. // IEEE Trans. 2002.
