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)

Hydrostatic pressure

• 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.
  

Physical probes

• 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

Uniaxial Stress

• Heat capacity using uniaxial-strain devices combined with a modified ac-heat capacity technique
