Spin dynamics in weakly and strongly interacting NiO nanoparticles
The spin dynamics of plate-shaped nanoparticles of NiO has been studied by inelastic neutron scattering and Mossbauer spectroscopy. A value of the in-plane anisotropy energy constant significantly larger than the bulk value has been measured. The temperature and field dependence of the energy of the antiferromagnetic resonance mode associated with this in-plane anisotropy has been studied.
Both Mossbauer spectroscopy and neutron scattering data show that the magnetic fluctuations are strongly affected by the strength of interparticle interactions.
