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
