Pa. Voltairas et Cv. Massalas, SIZE-DEPENDENT RESONANCE MODES IN FERROMAGNETIC-SPHERES, Journal of magnetism and magnetic materials, 124(1-2), 1993, pp. 20-26
In the present work we deal with the size-dependent resonances in smal
l ferromagnetic spheres. The analysis is based on the theory of microm
agnetism, the work of Aharoni, and an optimization technique. Numerica
l results are presented for the resonance field, as well as for the re
sonances modes and the magnetization configuration in the material. Th
e role of parameters entering into the problem is extensively discusse
