Electron Microscopy of Ferrites

This paper describes some electron microscopy studies of magnetic ferrites with special emphasis on LiFe 4 O 8 and including some results on NiFe 2 O 4 and SrFe 12 O 18 , The paper is concerned with analysis of the crystallography, defect structure, and phase transformations and their relations to magnetic properties, viz. coercivity and hysteresis characteristics.
