Abstract

Measurements have been performed of cubic-tetragonal transition temperatures and magnetic properties on a set of those samples of the binary system CuO-Fe/sub 2/O/sub 3/ which contain Fe/sub 2/O/sub 3/ more than stoichiometric CuFe/sub 2/O/sub 4/. A marked magnetic hardening was observed on a sample of 40CuO.60Fe/sub 2/O/sub 3/ which has been verified, through the X-ray analyses and measurements of Moessbauer spectra, to result from the precipitation of ..cap alpha..-Fe/sub 2/O/sub 3/ taking place during annealing.
