Abstract

In the present work we study the dispersion relation of magnetostatic modes in the spherical core@shell structure of purely conductive material (PCM) as core and soft ferromagnetic (FM) as shell. The PCM is a sphere of radius r 1 covered by an FM shell of inner radius r 1 and outer radius r 2 . To solve the equation, a transformation of the Walker equation in the FM region based on the solution proposed by Plumier was performed. The obtained solutions are consistent with those obtained by approximate methods proposed in the literature.
