ABSTRACT
Nanohybrid structures of FePt and BaTiO3 with bifunctional properties were synthesized by a two step synthesis procedure including solid state and solvothermal methods. Two different compositions of FePt and BaTiO3 nanoparticle samples were synthesized. The hybrid composite, having the lower FePt concentration, exhibited bifunctionality including superparamagnetism with a blocking temperature near room temperature and ferroelectricity at ambient conditions. Magnetocapacitive measurements of this bifunctional FePt–BiTiO3 sample showed behaviour typical of weak magnetoelectric coupling. This synthetic approach provides a general method for preparing advanced multifunctional and technologically important ceramic–alloy hybrids.
