Abstract

A series of measurements to study the low temperature dynamics of an interacting magnetic nanoparticle system were performed. The striking memory effects in the dc magnetization and magnetic relaxation that supported the existence of a spin-glass-like phase in interacting magnetic nanoparticles was demonstrated by the results. The results showed that an asymmetric response with respect to temperature change that supports a hierarchical picture was observed.
