Abstract

Zero valent iron microclusters were stabilized inside the pore structure of A-type zeolites. The cage diameter of the matrix was 1.1 nm. Mößbauer spectra show superparamagnetic behaviour down to at least 77 K. Below 10 K, slow relaxation of most of the superparamagnetic moments was observed. Information on the magnetic properties was obtained from the Mößbauer spectra below 4.2 K and from measurements in an external magnetic field applied parallel to the gamma beam. Evidence has been found for both bulk-like and non-crystalline iron clusters.
