Structural, magnetic and dielectric properties of Y doped BiFeO3

•The doping of Y helped in reducing the impurity phase of BiFeO3.•All the Y doped samples are found to exhibit peaks in magnetization.•Y doped BFO might be considered for future device applications.

With a view to understand the influence of doping Bismuth ferrite with Yttrium on structural, magnetic and dielectric behavior, a series of samples were prepared by the solid state reaction technique. After characterizing the samples with XRD and SEM studies, magnetic and dielectric measurements were carried out. The impurity phase of Bismuth ferrite is found to disappear with increasing Y doping concentration and finally the sample with x = 0.2 is found to be free from secondary phases. The dielectric constant is also found to exhibit two transitions and efforts were made to explain the observed behavior.
