Table 1 The calculated lattice parameters (a, b, c, α, β, and γ), unit cell volumes, and average crystallite sizes of the (La0.6Pr0.4)0.67Ca0.33MnO3 nanoparticles post-annealed at (A) 700 °C, (B) 800 °C, (C) 900 °C, and (D) 1000 °C for 5 h. 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
