Anisotropic phonon density of states: the application of Rietveld and Mössbauer texture analysis in aligned powders

Measuring the anisotropic properties of materials, such as phonon densities of states, is possible on an anisotropic polycrystal with a well known orientation distribution function (ODF). With this purpose, the ODF is characterized by Rietveld and Mössbauer texture analysis.
