| Abstract |
Owing to the technological importance of M-type hexaferrites of general formula MFe12O19 (M = Ba, Sr and Pb) and their substituted analogues, a staggering number of research activities on their synthesis, magnetic properties and thermal properties are being pursued in recent years. However, many critical issues on the effect of aliovalent ion substitution either on the M-site or Fe-sites are still unexplored. This paper deals with a survey of crystallochemical and thermodynamic properties of this important class of ferrimagnetic oxides. |
