Abstract

The aim of this research project is to study low temperature crystallographic properties of intermetallic compounds prepared at the Optical and Magnetic Properties of Solids Group from the IFGW. We would like to study several scientific cases where the crystallographic information of single crystals at low temperature (below 10 K) can unravel important physical properties of different classes of materials such as magnetic, superconductors and thermoelectric compounds. We would like to implement the infrastructure to perform single crystal diffractometry at low temperatures (~2 K) to study low temperature phase transitions, crystallographic distortions and new conformational structures in thermoelectric systems. Furthermore, we intend to use this instrumentation in single crystal structural studies in intermetallic compounds of strongly correlated electrons systems. (AU)
