Abstract
The radio frequency (rf) susceptibility of a series of yttrium gadolinium iron garnets was investigated in the frequency range 40–160 MHz. Resonant behavior was observed for most compositions, and the effective mass of the domain walls and the Landau‐Lifshitz damping parameter were determined. The damping parameter was found to be approximately the same for the yttrium and gadolunium ions with the value λ ≃ 1.6×107 rad sec−1.Keywords
