Structural, Magnetic and Dielectric Properties of Bi0.9Re0.1FeO3(Re = La, Sm, Gd and Y)

Abstract: With a view to understand the influence of rare earth ion doping on the structural, magnetic and dielectric properties of bismuth ferrite, a series of samples were prepared by the solidstate reaction method. After characterizing the samples with XRD and SEM studies, the magnetic and dielectric measurements were carried out. It is interesting to note that the two impurity phases, viz., orthorhombic Bi 2 Fe 4 O 9 and cubic Bi 25 FeO 40 observed in undoped bismuth ferrite are found to vanish with rare earth dopin… Show more

“…The experimentally observed and calculated Rietveld refined patterns of one representative sample (BGFO compound) along with the difference in both the patterns are shown in Figure 1b and the refined crystallographic data are given in Table 1. The results are in good agreement with those available in the literature [5,20] and no structural changes have been observed. There is an almost linear variation of the lattice parameters a, b, and c and the variations are in accordance with the well-known lanthanide contraction phenomenon.…”

“…Increasing in temperature destroys antiferromagnetic ordering and magnetization is enhanced. Similar behavior of magnetization with temperature relation was observed in other Fe-containing materials [18], where increase in the magnetization was explained by the creation of Fe 2+ ions in the structure built of Fe 3+ .…”
