Abstract

The optical constants of RF planar magnetron sputtered Ni-Al₂O₃ films are reported for the 0.3-2.5 μm wavelength range. The data are interpreted in terms of Maxwell-Garnett and Bruggeman effective medium theories. The effect of atomic Ni dispersion in the Al₂O₃ matrix on the effective medium formalism is discussed.
