Abstract
Collective magnetic properties were studied for randomly dispersed ferromagnetic fine particles with dipolar interactions. The sample was a frozen iron-nitride magnetic fluid containing uniform single-domain particles. The results show divergences of non-linear susceptibility and of relaxation time. These indicate the existence of a spin glass-like phase transition. At lower temperatures, novel aging phenomena were observed as seen in spin glasses.
