Structural Transformations and Multiferroic Properties of Bi1−xEuxFe0.95Co0.05O3 (x = 0.05, 0.10, 0.15, and 0.20)

Bi1-xEuxFe0.95Co0.05O3 (x=0.05, 0.10, 0.15, and 0.20) nanoparticles were prepared through the sol-gel technique. Its structure, local electronic structure, magnetic and electric properties were systematically investigated. X-ray diffraction data show (104), (110) bimodal alignment and high angular migration, indicating that with the increase of Eu substitution at Bi site, the structure of BFO undergoes a continuous change in crystal structure. The hysteresis loop and the FC/ZFC curve show how magnetism varies with the size of the field and temperature. Finally, the causes of magnetic changes were analyzed by studying SXAS and hysteresis loops.
