Abstract
The magnetic properties of iron-containing ETS-IO zeolite and its calc ined variety have been studied by magnetic measurements, The results a re consistent with the presence of paramagnetic ions and superparamagn etic clusters. Calcination results in a shift of the blocking temperat ures, although their frequency dependence cannot be ascribed to non-in teracting clusters. The hypothesis of cluster-glass like behaviour is discussed.
