PPMS-based set-up for Raman and luminescence spectroscopy at high magnetic field, high pressure and low temperature

Abstract

We present an experimental setup permitting Raman and luminescence spectroscopy studies in a commercial Physical Properties Measurement System (PPMS) from Quantum Design. Using this experimental setup , gaseous, liquid and solid materials, in bulk or thin film form, may be investigated. The setup is particularly suitable for the study of the spin-lattice coupling in strongly correlated oxide materials utilizing several different stimuli, e.g. magnetic and electric fields, high pressure and low temperatures. Details for the Raman extension, sample holder assembly and optical design, as well as data acquisition and measurement routine are described. Finally, we present exemplary results collected using the setup , measured on reference materials, as well as on a correlated transition metal oxide.
