摘要: Abstract The magnetic properties of magnesium ferrite (MgFe2O4) prepared by a wet-chemical method and ceramic have been investigated means Mossbauer spectroscopy, susceptibility, magnetization measurements. temperature dependence the spectra has shown existence superparamagnetic clusters in MgFe2O4 sample this is confirmed observing maximum low-field ac susceptibility versus On other hand, preparation exhibits relaxation behavior at high temperatures. It found that annealing gives close to obtained with usual method. These observations suggest depend on particular preparation.
