Thermodynamic, magnetic and electrical transport properties under extreme conditions of temperature, magnetic field and pressure
High pressure techniques
(40 mK < T < 350 K, up to 16 T in the high pressure lab)
- Development of new pressure cells (e.g. miniature pressure cell for specific heat experiments, pressure cell for neutron scattering studies in high magnetic fields, Bridgman-type cell for use in PPMS, etc.
- Electrical transport, including electrical resistivity, magnetoresistance, Hall effect, Shubnikov-de Haas oscillations in piston-cylinder type pressure cells, Bridgman type cells and diamond anvil cells (DAC's)
- AC-susceptibility in piston-cylinder type pressure cells
- Magnetization in piston-cylinder type pressure cells using a Faraday magnetometer or MPMS (Quantum Design) and in a DAC
- Specific heat(absolute values) using piston-cylinder type pressure cells and ac-heat capacity (relative values) in piston cylinder and Bridgman type cells
- Scattering and spectroscopy methods under pressure in collaboration with other groups
