Summary: This study manufactured Pb(Ni1/3Nb2/3)O-3-Pb(Zr,Ti)O-3-BiFeO3 ceramics substituted with Pb(Mg1/2W1/2)O-3 for application in piezoelectric speakers, through MnO2 addition, and found that the non-doped specimen exhibited the maximum piezoelectric properties. The x = 0.2 composition ceramics were deemed suitable for low-temperature sintering multilayer piezoelectric actuators due to their low dielectric constant and high d(33) values with increasing numbers of layers.

Summary: In this study, Pb(Mg1/3Nb2/3)O-3-Pb(Zr,Ti)O-3 (PMN-PZT) single crystals doped with hardener Mn were used to develop a high-output magneto-mechano-electric (MME) generator. By doping with 0 to 0.8 mol% hardener Mn, the dielectric constant and dielectric loss of the PMN-PZT crystal gradually decreased. The Mn-modified MME device achieved an improved magnetoelectric coefficient of 783.09 V per cm center dot Oe and a root mean square output power of 3.3 mW when an alternating current magnetic field of 8 Oe was applied, which is 1.8 times higher than that of the MME generator without Mn-doping.

Summary: In this study, we experimentally investigated the strain-mediated converse magnetoelectric effect in multiferroic heterostructures. The results showed that only the heterostructure with a specific structure can modulate its remanent magnetization state under strain, while strain has no effect on heterostructures with other structures. Therefore, the formation of a specific structure is crucial for achieving an effective converse magnetoelectric effect.
