Abstract

Lead-free multiferroic ceramic composites of x Ni0.93Co0.02Mn0.05Fe1.95O4−(1–x) Na0.5Bi0.5TiO3 (x NCMF−(1–x) NBT, where x=0.1, 0.2, 0.3, 0.4 and 0.5mol fraction) were synthesized by spark plasma sintering (SPS) in conjunction with high-energy ball milling. The phases, dielectric, piezoelectric, ferroelectric, magnetic and magnetoelectric properties of the composites were analyzed. The composites were composed of a mixture of spinel and perovskite phases. All the composite samples exhibited both apparent ferroelectric and ferromagnetic characteristics as well as considerable magnetoelectric (ME) effects. The maximum value of the ME voltage coefficient of the composites was quite high, being up to ~670mVcm−1Oe−1 for the 0.5NCMF−0.5NBT composite. Overall, the synthesized composites were promising in terms of electrical, magnetic and magnetoelectric properties, indicating that the SPS is a promising method of fabricating ME composite materials.
