Abstract
The contribution of in iron garnets to the first-order anisotropy constant and to the microwave loss is highly nonlinear with respect to the concentration and is shown to be strongly dependent on the lattice constant. The value of the anisotropy constant per Pr ion goes from -18× to about +3× erg/ as the lattice constant increases from 12.4 to 12.7 Å. The microwave linewidth of Sc is 21 times narrower than expected from the extrapolation of the low-concentration data of in yttrium iron garnet.
