摘要：

The influence of the dipole-dipole interaction on the dynamics of monodispersive ensembles of magnetic nanoparticles have been studied by Monte Carlo simulations. An increased interaction strength drives the system from a state with only individual particle relaxation al all temperatures to a state where collective phenomena govern the dynamics at low temperatures. The collective nature of the dynamics is reflected in the appearance of magnetic ageing and a dramatically broadened relaxation function.
