Enhanced magnetic and ferroelectric properties of textured multiferroic Bi5Ti3FeO15-CoFe2O4 ceramics prepared by plasma activated sintering
2017
Abstract Textured multiferroic Bi 5 Ti 3 FeO 15 -CoFe 2 O 4 (BTFO-CFO) ceramics were prepared via microwave hydrothermal synthesis followed by plasma activated sintering. BTFO-CFO ceramics with CFO nanoparticles distributed between the BTFO layers exhibit a high degree of texture ( f =0.8) along the c-axis crystallographic orientation, which was confirmed by a combination of XRD, SEM and TEM. BTFO-CFO composite ceramics exhibit desirable magnetic and ferroelectric properties due to the ferromagnetic phase (CFO) and textured ferroelectric phase (BTFO). The current work provides a feasible method to fabricate textured multiferroic composite ceramics.
