Abstract
Multiferroic 0.6Bi(1-x)Dy x FeO 3 -0.4PbTiO 3 (x=0, 0.10) nanoparticles were synthesized via sol-gel route. The effect of rare earth Dy 3+ ion substitution on structural, magnetic and dielectric properties of BiFeO 3 -PbTiO 3 system has been studied. Rietveld refinement studies of X-ray diffraction profiles reveal that system exhibit cubic (Pm3m) and tetragonal (P4mm) crystal structure for x = 0 and single cubic (Pm3m) phase for x = 0.10. Experimental results show that Dy 3+ doping suppresses the modulated spin cycloid of BiFeO 3 results in net remnant magnetization. Dielectric studies show that the conductivity of the sample decreases with Dy 3+ ion substitution in the composition, which indicates that Dy 3+ doping suppresses the oxygen vacancies.
