Description
The effective g-factor, geff, the uniaxial anisotropy, Hu, Gilbert's damping parameter, α, and linewidths ΔH parallel and ΔH perpendicularto for liquid phase epitaxially grown thin films of composition Eu0.6Y2.4GayFe5-yO12 (0.9 ≤ y ≤ 1.6) have been investigated in the spin compensation region. It is found that the spin compensation point (ys) occurs at y 1.29, while the magnetization compensation point (ym) occurs at y = 1.22 giving ys - ym = 0.07. The damping parameter α as well as γeff/α for both the parallel and perpendicular resonance configurations are found to diverge at the S-compensation point while the anisotropy field diverges at the M-compensation point.
