Structural distortion, ferroelectricity and ferromagnetism in Pb(Ti1−xFex)O3

Recently interest in finding magnetoelectric coupling in Fe substituted PbTiO3 is observed. Synthesis of single phase PbTi(1−x)Fe(x)O3 is a challenge which we report for 0 ≤ x ≤ 0.5. PbTiO3 is a strong ferroelectric. Fe substitution at the Ti site may lead to a potential magnetoelectric multiferroic material maintaining the non-centrosymmetric lattice distortion due to elongation of Ti-O octahedral in PbTiO3 intact. The synthesis chemistry is a determining factor on the pure phase. Valence state, size and coordination of substituting Fe is a determining factor of how the lattice distortion will get modified deciding several changes including oxygen deficiency, etc., and results in variations of electronic/magnetic properties including ferroelectricity and magnetism. We investigate the structural and electronic properties and correlate discussing briefly the introduced magnetic properties and subsequent structural changes linked to ferroelectricity.
