Abstract

The structural and magnetic study of the pseudo-binary multiferroic (1 x)BiFeO3 (x)SrTiO3 has been investigated as a function of composition and temperature. In contrary to the previous studies, detailed examination revealed that the reported anomaly in the magnetization at x-0.30 does not occur at the composition induced rhombohedral-cubic phase boundary, but within the rhombohedral phase itself. The rhombohedral to cubic transition occurs at x > 0.4. Evidence of magneto-elastic coupling near the Neel temperature and nucleation-growth mode of the rhombohedral-cubic transformation, with both the phases coexisting over a range of temperature was found.
