Description
The relaxation of the local ordering of nanoparticles induced by an external magnetic field in a concentrated Cobalt ferrofluid was studied by stroboscopic polarised small-angle neutron scattering. Magnetic and nuclear correlations were found to decay exponentially within a characteristic time of few seconds. The local hexagonal particle arrangements with aligned moments transform gradually to uncorrelated segments of dipolar chains. The dynamics is influenced by dipole-dipole interactions
