Abstract

This paper deals with super or collective paramagnetism and the possible applications of Mössbauer spectroscop to collectively paramagnetic systems such as oxides, catalysts with metal dispersions on the surface of diamagnetic supports, and dispersion within a silicate matrix. The last named area represents a superparamagentic system, developed and studied in our laboratory, Papers dealing with the Mössbauer spectra of superparamagnetic systems are reviewed and the possibilities of relationships between the relative line intensities of quadrupole-split Mössbauer spectra and the cluster sizes of superparamagnetic systems are considered.
