Abstract
The solid solution of multiferroic BiFeO3 with antiferroelectric NaNbO3 ie Bi1−x Na x Fe1−x Nb x O3 for x = 020 025 030 032 038 and 040 prepared by means of high temperature solid state ceramic method are presented Xray diffraction analysis confirms the singlephase formation Structural transformation in solid solution from rhombohedral to cubic phase has been observed with increasing NaNbO3 concentration The field emission scanning electron microscopy shows the formation of dense ceramic with a nonuniform grain size Room temperature Raman studies also confirms a structural transformation in solid solution with increase in NaNbO3 concentration The structural transformation in solid solution has been explained on the basis of lattice strain induced by dopingAuthors are thankful to Department of Pure and Applied Physics Guru Ghasidas Vishwavidyalaya for facilities generated under SAPUGC FISTDST program The author HST is thankful to University Grant Commission New Delhi India for financial assistance through MRP F No 41–954/2012SR One of the authors MD is thankful to Guru Ghasidas Vishwavidyalaya for financial assistant through UGC scholarship Authors are also thankful to Prof G D Varma Department of Physics Indian Institute of Technology Roorkee India
