In this paper, a approach which is based on Landau-Lifshitz ferromagnetic resonance (LL-FMR) model has been developed to calculate the complex permeability of magnetic particles/insulator matrix composite. It has found that the LL-FMR model can be used to compute the intrinsic permeability of a magnetic particle with different alignments of its magnetic domains with the respect to the incident wave. Through integration with respect to its resonant frequency, this method offers a neat closed-form formula for the case of isotropic composite. Its results compared relatively well with our previous method which computes the isotropic permeability by taking the average of the permeability of a large number of randomly oriented magnetic domains with respect to incident wave based on the LL-G model. For carbonyl bcc-Fe and Fe3 O4, the calculated permeability agrees relatively well with the measurement results. © 2010 American Institute of Physics.||Source Title:||Journal of Applied Physics||URI:||http://scholarbank.nus.edu.sg/handle/10635/86203||ISSN:||00218979||DOI:||10.1063/1.3383054|
