Expertise :

Magnetic nanoparticles
Characterization of both macroscopic samples and thin-film assemblies of nanoparticles, including exchange-biased nanosystems:

  • Measurement of M(T) (2-400 K) and M(H) (±50 kOe) in both ZFC and FC modes
  • ZFC and FC magnetization
  • TRM-like experiments
  • Hysteresis loops
  • DCD
  • Magnetic memory and viscosity
  • AC magnetization
  • Analysis of FORC curves

Polynuclear metal ion complexes
Determination of the exchange parameters

  • Measurement of M(T) and M(H)
  • Determination of the exchange parameters by best fit to Van Vleck function (full Hamiltonian diagonalization or Kambè vector method) using both Nelder-Meade and Levenberg-Marquardt methods with full error analysis

Superconducting materials
Determination of the critical temperature

Equipment :

  • Quantum Design MPMS XL-5 SQUID Magnetometer (± 5 T, 2 – 400 K, DC, RSO, AC susceptibility, ultra low field)
