Optical Properties of Dilute CuAl${}_{1-x}$Fe${}_x$O${}_2$ Delafossite Alloys

Abstract

For powder samples of CuAl${}_{1-x}$Fe${}_x$O${}_2$ ($x=$ 0, 0.01, 0.05, and 0.1), measured optical properties are compared with model simulations and phonon spectra are compared with simulations based on weighted dynamical matrix approach.
