Magnetic susceptibility and magnetization fluctuation measurements of mixed Gadolinium-Yttrium Iron Garnets

S. Eckel, A. O. Sushkov, S. K. Lamoreaux

We study the magnetic properties of Gadolinium-Yttrium Iron Garnet (${\text{Gd}}_x{\text{Y}}_{3-x}{\text{Fe}}_5{\text{0}}_{12}$, $x=3,1.8$) ferrite ceramics. The complex initial permeabi…
