摘要：

We derive a sum rule on the dynamic magnetic dissipation in magnetic materials. We obtain a bound on the weighted sum of the gyromagnetic losses over the whole spectral range. Bounds are established for a fairly large class of bull; and composite magnetic materials, and shown to agree with experiment. It is also shown that a close approach to this bound can be experimentally attained.
