Abstract

We report the structural, ferroelectric (FE), piezoelectric, and converse magnetoelectric (ME) effects in a series of Cr/Mn doped BiFeO3-Bi0.5K0.5TiO3-based (BF-BKT) single crystals. The Cr and Mn co-doped BF-BKT crystal (i.e., CrMn04) shows a large switchable polarization of 12ΔP ∼ 59.4 μC/cm2 and large-signal piezoelectric coefficient d33* at room temperature, and nearly thermally stable piezoelectric coefficient of d33 ∼ 212 pC/N below depolarization temperature Td ∼ 358.7 °C. A high DC resistivity of ρ > ∼1.0 × 105 Ω cm for T < ∼346.5 °C was also observed in CrMn04 crystal. All samples exhibit coexistent antiferromagnetic and FE orders and evident electric control of magnetism. The simultaneous existence of good performance of ferroelectricity, piezoelectricity, and converse ME effects in especially the CrMn04 crystal suggests its potential application in multi-functional devices.

期刊介绍： Applied Physics Letters (APL) features concise, up-to-date reports on significant new findings in applied physics. Emphasizing rapid dissemination of key data and new physical insights, APL offers prompt publication of new experimental and theoretical papers reporting applications of physics phenomena to all branches of science, engineering, and modern technology. In addition to regular articles, the journal also publishes invited Fast Track, Perspectives, and in-depth Editorials which report on cutting-edge areas in applied physics. APL Perspectives are forward-looking invited letters which highlight recent developments or discoveries. Emphasis is placed on very recent developments, potentially disruptive technologies, open questions and possible solutions. They also include a mini-roadmap detailing where the community should direct efforts in order for the phenomena to be viable for application and the challenges associated with meeting that performance threshold. Perspectives are characterized by personal viewpoints and opinions of recognized experts in the field. Fast Track articles are invited original research articles that report results that are particularly novel and important or provide a significant advancement in an emerging field. Because of the urgency and scientific importance of the work, the peer review process is accelerated. If, during the review process, it becomes apparent that the paper does not meet the Fast Track criterion, it is returned to a normal track.
