| Abstract | ||
| We report a comparative study of rare-earth ions substituted Bi0.6Sr0.4FeO3(BSFO) crystal for; BSFO, Bi0.57Sr0.4Y0.03FeO3, Bi0.57Sr0.4Nd0.03FeO3, Bi0.57Sr0.4Ce0.03FeO3, and Bi0.57Sr0.4La0.03FeO3, respectively. The samples were successfully synthesized using flash autocombustion reaction. X-ray diffraction analysis reveals that the crystal structure is rhombohedral and a clear hexagonal grain growth habit is seen by FESEM microstructure. The doping of BSFO improved the magnetic properties specially Y3+, Nd3+ ions. While Ce3+ improved the electrical conductivity. We argue that the addition of RE is likely to suppress the spiral spin modulation and at the same time increase the canting angle which favors the enhanced ferromagnetism. | ||
