Measurements in a wide temperature (0.005 K - 300 K) and magnetic field range (0 - 18 T) and pressure range (0 - 20 GPa) can be performed in the laboratory:

Set up for thermal conductivity and thermal transport measurements on a rotating sample holder.

• several dilution refrigerators for standard measurements cryomagnets up to 18 T can be used with different cryostats

• 15 T magnet for measurements down to 0.005 K

• ³He cryostat, ⁴He cryostats

• very low temperature thermal transport measurements (T > 0.005 K) thermoelectric power

• measurements specific heat to very low temperatures

• possibility of continuous sample rotation in dilution

• quantum oscillations measurements

• fast sample characterisation can be performed in an PPMS from Quantum design with 9 T magnet and ³He option


High pressure experiments

Sample with four contacts for resistivity measurements in diamond anvil cell.

• piston cylinder pressure cells for transport, susceptibility, thermal expansion, and neutron scattering experiments
(0 - 3 GPa, 25 mK - 300 K, 0 - 18T)

• diamond anvil cells for transport, susceptibility, and specific heat experiments
(0 - 20 GPa, 25 mK - 300 K, 0- 18 T)

• For diamond anvil cells we have the possibility to change the pressure continuously at low temperature what allows to determine very precisely the high pressure phase diagram.


Single crystal growth:

PrOs₄Sb₁₂ single crystal grown out of Sb flux (top left), single crystal growth of UCoGe in the tetra arc furnace (top right)) and Sr12Ca₂Cu₂₄O₄₁ crystal grown by the Traveling Solvent Float Zone (TSFZ) technique in a mirror furnace (bottom).

The focus of single crystal growth is to obtain very pure, high quality crystals. Depending on the material, different techniques can be used
• tetra arc furnace
• mirror furnace
• flux method
• bridgman technique
• Czochralski method
