Abstract
Far-infrared spectra of magnetodielectric Dy3Fe 5O12 garnet were studied using a combination of transmittance, reflectivity, and rotating analyzer ellipsometry. In addition to purely dielectric and magnetic modes, we observed several hybrid modes with a mixed magnetic and electric dipole activity. Using 4×4 matrix formalism for materials with μ(ω)≠1, we modeled the experimental optical spectra and determined the far-infrared dielectric and magnetic permeability functions. The matching condition μ(ωh)Se= ω(ωh)Sm for the oscillator strengths S e(m) explains the observed vanishing of certain hybrid modes at ωh in reflectivity. © 2011 American Physical Society.
