Table 2 The calculated lattice parameters (a, b, c, α, β, and γ), unit cell volumes, and average crystallite sizes of the (La1 − xPrx)0.67Ca0.33MnO3 nanoparticles post-annealed at 800 °C with different Pr-doped concentrations (x = 0.0–0.5) Lattice parameters within ± 0.0003(a, b, c) are calculated from the XRD data. Average crystallite sizes within ± 1 are calculated using the Scherrer’s equation
