In this study, pure and single-phase Bi5Ti3FeO15 (BTFO) ceramics were prepared by the standard solid-state sintering method. Magnetic and Mössbauer spectroscopy measurements revealed the paramagnetic behaviour of the material down to 3.7 K. However, the measurements of the magnetoelectric (ME) effect proved the existence of a strong ME coupling in the samples. It was shown that the optimisation of BTFO production process and applying additional electrical poling to the material at elevated temperature allowed a significant increase in the strength of ME coupling. Mössbauer spectroscopy measurements revealed a distribution of the quadruple splitting values because of the location of iron ions in different, symmetrically non-equivalent positions in the crystalline lattice. It is assumed that the presence of ME coupling in the paramagnetic-like BTFO compound is caused by the clustering of Fe3+ ions in the perovskite-like lattice. |
