Abstract
The FMR parameters of an infinitly long ferromagnetic cylinder with arbitrary value of conductivity are calculated neglecting the exchange term in the equation of motion. For low resistivity magnetic materials the resonance field, linewidth, and asymmetry of the absorption curve are computed as a function of the ratio a/δ of the radius of cylinder to the skin depth . These dependences are compared with the experimental results on low-resistivity manganese-iron ferrites. Further an approximative formula is derived for the radiation contribution to linewidth, and for the resonance field shift depending on conductivity.
