Room temperature XRD patterns of Bi1-x Nd x Fe0.97Ti0.03O3. Indices for x = 0.1, 0.15, and 0.25, correspond to the rhombohedal, FE (R3c), the PbZrO3–like, AFE (Pbam), and the orthoferrite, PE (Pnma) structures, respectively.
Secondary electron images from fracture surfaces of Bi1-x Nd x Fe0.97Ti0.03O3 ceramics.
Room temperature Raman spectra of Bi1-x Nd x Fe0.97Ti0.03O3 ceramics. Characteristic R3c, PZ, and orthoferrite modes are indicated by R, PZ, and O, respectively.
DSC curves of Bi1-x Nd x Fe0.97Ti0.03O3 ceramics. T N for the ceramics is indicated within the boxed region of the plot.
Latent heat vs composition for Ti-doped Bi1-x Nd x FeO3. Error bars correspond to standard deviation of the latent heats obtained from different DSC heating cycles.
Dilatometry curves of all ceramics. The phase transition temperatures correspond well with DSC results.
Permittivity vs temperature curves of Ti-doped Bi1-x Nd x FeO3 ceramics.
Dielectric loss vs temperature for Bi1-x Nd x Fe0.97Ti0.03O3 ceramics.
Plot of T C vs Nd content obtained from DSC, dilatometry and dielectric measurements.
Latent heat associated with the phase transition at T C for 3% Ti-doped Bi1-x Nd x FeO3.
