An Automated Setup for Investigation of Anisotropy of the Gruneisen Parameter of Solids in the Temperature Range 77-350 K Using the Photoacoustic Technique

摘要

An automated setup for studying the anisotropy of the Gruneisen parameter of solids in the temperature range 77-350 K using the photoacoustic technique is described. The serviceability of the setup was tested at low (77-300 K) and high (300-350 K) temperatures on strontium titanate and triglycine sulphate single crystals, respectively.
