摘要：

The magnetic properties of polymers prepared by polymerization of the magnetic cluster Mn12O12(acrylate) 16 with various portions of ethyl acrylate as co-monomer are reported. According to SAXS studies, the clusters are homogeneously distributed in the polymer. Ac susceptibility measurements show superparamagnet-like behaviour of the cluster-crosslinked polymers with relaxation following an Arrhenius law with tau(0) = 4-8 x 10(-8) s and an energy barrier in the range 45-65 K.
