摘要：

We report here on our latest investigation of the spin fluctuations of Fe nano-particles embedded in an alumina matrix by means of Neutron spin-echo spectroscopy. By completing our data to lower Q, we find evidence of a slowing down of the super-paramagnetic fluctuations as expected in the presence of inter-particle correlations. (C) 2000 Elsevier Science B.V.
