Inelastic Neutron Scattering Investigations of Molecular Nanomagnets
Inelastic neutron scattering, probing the temporal spin¿spin correlation at the microscopic scale, is a
powerful technique to study the magnetic behaviour of molecular nanomagnets. Experiments at different
energy scales and different energy-transfer resolution allow precise determinations of the parameters
defining the effective Hamiltonians used to model the diverse physical properties exhibited by this class
of materials. The intrinsic disadvantage of the technique (low flux, requiring a sample mass in the gram
scale) is over-compensated by the large amount of information that can be straightforwardly extracted.
Zero-field splittings and exchange interactions can be determined with a large degree of confidence,
shedding light on important issues such as magnetization tunnelling in giant-spin clusters, or the occurrence
of quantum coherence phenomena and their consequences on macroscopic observables.
