| Abstract: | The Mie scattering intensity of a magnetic sphere has been derived by extending the classical Mie scattering approach to a media where the dielectric constant is no more a real number but a tensor of gyromagnetic form. Using a perturbation method the equations of the electromagnetic field are derived. This model has been applied to Co, Ni and Fe spheres. For an incident plane wave the magnetization effect could be detectable in the special incident case where the magnetic field of the incident plane wave is polarized along the magnetization direction. This magnetization effect is most important for the finger pattern of the backscattering intensity. Magnetic Mie scattering is still significant for a magnetic sphere of radius larger than 10 nn for Co and 6 nm for Fe. | |
