    Abstract

    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 ?0 = 4-8 × 10-8 s and an energy barrier in the range 45-65 K.
