The present paper is particularly devoted to the damping effect in ferromagnetic materials. We are interested in determining the sensitivity of the LLG method solution to the phenomenological damping parameter a. We discuss the behaviour of the global weak solutions with finite energy of the Landau-Lifshitz equations when the damping parameter a tends either to 0 (underdamped case) or (overdamped case).
In questo articolo si tratta l'effetto damping nei materiali ferromagnetici. In particolare, ci si occupa di determinare la sensibilità della soluzione ottenuta con il metodo LLG rispetto al parametro di damping a. Si analizza qui il comportamento della soluzione debole globale ad energia finita delle equazioni di Landau-Lifshitz quando il parametro di damping a tende verso 0 (underdamping) o verso (overdamping).
