Description The effective g-factor, g(eff), the uniaxial anisotropy, H(u), Gilbert's damping parameter, alpha, and linewidths DELTAH(parallel-to) and DELTAH(perpendicular-to) for liquid phase epitaxially grown thin films of composition Eu0.6Y2.4GayFe5-yO12 (0.9 less-than-or-equal-to y less-than-or-equal-to 1.6) have been investigated in the spin compensation region. It is found that the spin compensation point (y(s)) occurs at y = 1.29, while the magnetization compensation point (y(m)) occurs at y = 1.22 giving y(s) - y(m) = 0.07. The damping parameter alpha as well as gamma(eff)/alpha 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.
