| description | In this research, a low temperature in-field 57Fe Mössbauer spectroscopy is used for investigation of anomalous magnetic properties of MnZn nanoferrite. Based on Mössbauer spectroscopy results, the reduced saturation magnetization of MnZn nanoferrite in respect to that of bulk sample is due to nonequilibrium cation distribution and spin disorder. The enhanced Curie temperature of MnZn nanoferrite in respect to that of bulk sample can be attributed to the strengthening of the (A)-O-[B] superexchange interactions due to an increase of the magnetic ion concentration in the (A) site. |
