Enhanced magnetisation in nanocrystalline high-energy milled MgFe2O4

The changes in magnesium ferrite (MgFe2O4) caused by high-energy milling are investigated by means of Mossbauer spectroscopy, magnetization measurements, and electron microscopy. The observed enhancement of the magnetization in nanoscale milled MgFe2O4 is discussed with respect to the mechanically i...

Zusammenfassung:	The changes in magnesium ferrite (MgFe2O4) caused by high-energy milling are investigated by means of Mossbauer spectroscopy, magnetization measurements, and electron microscopy. The observed enhancement of the magnetization in nanoscale milled MgFe2O4 is discussed with respect to the mechanically induced cation redistribution and spin canting. (Author)
