First principle band-structure calculations
We use a variety of highly sensitive tools to probe the physical properties of single crystals of less than 100 microns to be investigated in high magnetic fields and low temperatures.
Highly sensitive cantilevers (10-12 EMU) allow to determine phase transitions, anisotropy and in superconductors and magnetic materials and to measure quantum oscillations in the normal state of superconductors and other exotic metallic systems.
Microcontacs using Focus Ion Beam
Focus Ion Beam allows to build up electrical contacts on micro-size crystals to be able to measure Hall effect and in-plane conductivity in high magnetic fields and at very low temperatures.
We have developed a new probe to investigate the specific heat of micron size single crystals as function of temperature and high magnetic fields.
