Structural and dielectric properties of Nd/Ca co-doped bi-ferrite multiferroics Available to Purchase

Single-phase polycrystalline samples of $Bi0.8Nd0.2−xCaxFeO3$ (x = 0.0, 0.1) were synthesized by chemical coprecipitation method. X-ray diffraction patterns accompanied by Rietveld-refined crystal structure parameters reveal the phase transition of $Bi0.8Nd0.1Ca0.1FeO3$ with rhombohedral R3c symmetry to triclinic structure of $Bi0.8Nd0.2FeO3$ sample. Frequency dependence of dielectric constant (ε') and dielectric loss (tanδ), infers enhancement of both ε' (tanδ) in narrow band gap of Nd/Ca co-doped BFO as compare to wide band pristine BFO.
