“…and was thus chosen as the magnetic phase. 30,31 Addition of Al 2 O 3 can reduce the sintering temperature of ceramic, and alleviate the ceramic cofiring mismatch issue. Addition of a small amount of Al 2 O 3 can result in the formation of a solid solution, thus facilitating sintering to a density close to theoretical, limiting crystal growth, and forming a microstructure with isometric crystals, 24 so it was chosen as the sintering aid.…”

Magnetoelectric composites have attracted widespread attention during the past few decades due to their strong magnetoelectric coupling effect and potential applications above room temperature. Ni 0.5 Zn 0.5 Fe 2 O 4 /Ba 0.8 Sr 0.2-TiO 3 composites have been prepared by the conventional high-temperature solid-state method and the effects of Al 2 O 3 addition on their microstructure, dielectric, ferroelectric, and magnetic properties studied. x-Ray diffraction (XRD) analysis confirmed the biphase structure of the composites. scanning electron microscopy (SEM) showed that addition of a certain amount of Al 2 O 3 can enhance the density and promote uniform growth of particle size. The sample with 1 wt.% Al 2 O 3 addition exhibited the largest dielectric constant and lowest dielectric loss (< 0.05 at 1 kHz) at high temperature (> 354°C). The sample with 3 wt.% Al 2 O 3 addition presented the best ferroelectric properties, with the highest values of residual polarization (P r = 2.2150 lC/ cm 2 ) and coercive field (E c = 30.6527 kV/cm) among the specimens. The remanent magnetization (M r ) and saturated magnetization (M s ) decreased with increasing Al 2 O 3 content. In short, addition of Al 2 O 3 caused changes in the grain size, density, and defects, and addition of a certain amount of Al 2 O 3 can improve the magnetoelectric properties.

“…Composite multiferroic materials take advantage of the ME coupling between two or more single-phase compounds without multiferroic properties, thus, the composite material with a good ME coupling effect is Z. Zeng et al / Processing and Application of Ceramics 14 [3] (2020) 223-230 formed. It was found that the ME coupling coefficient of composite materials was several times higher than that of single-phase materials [14][15][16]. Composite multiferroic materials are generally composed of ferroelectric and ferromagnetic phase materials.…”

In this paper, xPbTiO 3 /(1-x)NiFe 2 O 4 (PTO/NFO, x = 0.1, 0.2, 0.3, 0.4 and 0.5) ceramic composites were prepared by mixing of sol-gel synthesized PTO and NFO powders, followed by their uniaxial pressing and sintering at 1150°C. The effects of PTO/NFO composition on crystal structure, surface morphology, electrical, magnetic and magnetoelectric coupling properties were studied. XRD results showed that the prepared ceramics contain only PTO and NFO phases without any impurity phase. The samples were relatively dense while the grains were evenly distributed. The dielectric constant and loss varied monotonically with the frequency for different molar ratios. The hysteresis loop of the composites with high amount of high resistance NFO phase (x = 0.1, 0.2) has the shape characteristic for a material with large leakage current. The samples with x = 0.1 showed the largest saturated magnetization, while the sample with x = 0.2 had the maximum remnant magnetization. It was also shown that the polarization was affected by the external magnetic field of 1 mT and the strongest ME coupling (relative polarization change of 15.4%) was observed for the 0.5PbTiO 3 /0.5NiFe 2 O 4 composite. In addition, the relevant calculation showed that the leakage mechanism may not be the main factor affecting the polarization of the obtained ceramics.
