Abstract
We present an experimental set-up permitting Raman and luminescence spectroscopy studies in a commercial Physical Properties Measurement System (PPMS) from Quantum Design. Using this experimental set-up, gaseous, liquid and solid materials, in bulk or thin film form, may be investigated. The set-up 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 set-up, measured on reference materials, as well as on a correlated transition metal oxide.
Highlights
Large efforts in the field of material science are spent on the development of novel functional materials
Strongly correlated electron systems are a class of materials that promise a multitude of applications
A Raman set-up for in-situ measurements of such properties at low temperature, magnetic field, electrical field and high pressure was constructed as an extension to the Quantum Design, Inc
Summary
Large efforts in the field of material science are spent on the development of novel functional materials. A Raman set-up for in-situ measurements of such properties at low temperature, magnetic field, electrical field and high pressure was constructed as an extension to the Quantum Design, Inc. Physical Properties Measurement System (PPMS) [10] - a standard cryogenic device in many laboratories world wide. An optical probe and an automatized data acquisition system were designed and linked with the already automatized temperature and magnetic field control provided by the PPMS.
