In this research, nanoparticles Bi1-x-yBayLaxFeO3 (BByLxFO (with values
(x = 0.0, 0.05, 0.1) and (y = 0.0, 0.15) synthesized by a sol–gel  method. The structural, microstructural and magnetic properties have been investigated, using X-ray diffraction, Raman scattering, field emission scanning electron microscopy (FE-SEM), FTIR  spectroscopy, and magnetometry measurements at room temperature. The refinement of X-ray diffraction pattern of samples indicates a phase transition from rhombohedral (R3c) to rhombohedral-tetragonal. In addition, The refinement of X-ray Assigned  lattice parameters and unit cell volume.  Analysis of FT-IR confirmed Perovskite structure of samples. The FE-SEM analysis show nanoparticle size it decreases with La  concentration. Finally, the hysteresis loop of nanoparticle BByLyFO shows ferromagnetic behavior, that may be attributed to the collapse of spin structure and modifying exchange interactions because of La+3  and Ba+2 co-doping. The remenant  magnetization of  BB0.15L0.1FO sample (Mr = 1.166 emu/g) is approximately two and half times greater than that of  BB0.15L0FO (Mr = 0.514 emu/g). This enhancement in magnetic properties at room temperature can play an important role for the practical applications.
