Abstract

Abstract The effective g-factor, g eff, the uniaxial anisotropy, H u, Gilbert's damping parameter, α, and linewidths Δ H ‖ and Δ H ⊥ for liquid phase epitaxially grown thin films of composition Eu 0.6Y 2.4Ga y Fe 5− y O 12 (0.9⩽ y ⩽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 α as well as γ eff/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.
