dc.description.abstractEn este trabajo se empleó un formalismo clásico para determinar los anchos de línea de la resonancia ferromagnética (FMR) en una película ultradelgada. Como resultado, se derivó una expresión analítica para el campo magnético efectivo del sistema propuesto. Se llevó a cabo la expansión en serie de Fourier de los campos magnéticos y la magnetización. Asimismo, se calcularon las componentes dinámicas del campo magnético efectivo en función del vector de onda. Subsecuentemente, se determinaron las componentes del tensor de susceptibilidad magnética transversal. Finalmente, se estableció la relación de dispersión para el sistema.spa
