Abstract
The optical properties of polycrystalline Ga 0.6Fe 1.4O 3 bulk are determined by spectroscopic ellipsometry from 0.73 to 6.45 eV. Complex dielectric function ε=ε 1+iε 2 spectra are obtained from the multilayer analysis. The ellipsometric data exhibit numerous optical structures, and the transition energies are accurately obtained by analyzing the second-energy derivatives of the data. The origins of the optical structures are explained in terms of Fe 3+ ligand field transitions and ligand-to-metal charge transfer transitions. © 2012 American Vacuum Society.
