| Popis: | A frequency dependence of the magnetic dissipation parameter (half-linewidth) $\Delta {H}$ for films of yttrium–iron garnet (YIG) was experimentally investigated in the interval of microwave frequencies 1.7–26 GHz. The $\Delta {H}$ value did not change over a frequency range of 2.2–26 GHz. The effect of conducting screens placed near a YIG film on the $\Delta {H}$ value was also studied experimentally. For a screened film, the value of $\Delta {H}$ exceeds $\Delta {H}$ for an unscreened film when the distance between the film and the metal screen was less than 40– $70~\mu \text{m}$ . |
