In this study, authors have synthesized bismuth ferrite using (i) solid state route and (ii) mechanochemical activation technique, The structural studies reveal the formation of bismuth ferrite of A(3-delta)B(5)O(12) type by mechanochemical activation technique and of ABO(3) type by conventional solid state route. In addition to the detailed studies on magnetic and electrical properties of both the samples, a comparative analysis has been done using Landau and Berry phase theory. Through this, an effort has been made to establish a relationship between magnetism and electrical polarization vis a vis magneto electric coupling in these samples. (C) 2013 Elsevier BM.
