? 2021 Elsevier B.V.Bi1-xSmxFeO3 (BSFO, x = 0, 0.05, 0.10, 0.15, 0.20) nanoparticles were prepared through tartaric acid-modified sol-gel technique. X-ray diffraction and scanning electron microscopy provide phase purity and nanocrystalline behavior (29–92) nm of pristine and doped BFO nanoparticles. The crystallite sizes of the studied samples ranged from 19.64 nm to 12.26 nm. The Rietveld refinement of XRD data demonstrated a good configuration of change in the crystalline structure. Structural phase analysis by XRD suggested that structural transformation from rhombohedral structure (R3c space group) to orthorhombic structure (Pnma space group) is observed in Sm substituted BFO nanoparticles. The ferromagnetic properties increase up to x = 15 % in the samples with enhancing magnetization. A large component of the orthorhombic phase for x = 20 % sample results from a drastic decrease in the ferromagnetic property due to collinear antiferromagnetic ordering correlated with VSM and EPR studies.
