Аннотация: Two numerical micromagnetic methods most suitable for calculation of the high frequency magnetic susceptibility of nanocrystalline thin films were considered in detail. The methods are based on the Landau-Lifshitz equation, linearized around the equilibrium state leading to an eigenvalue problem or solved using an undetermined coefПоказать полностьюficients technique. An analysis and estimation of an efficiency of the methods were carried out. Several conclusions about their advantages and shortcomings, as well as specifics of their practical application were drawn.
