| 英文摘要 | Superlattices (sls) consisting of multiferroic bifeo3 (bfo) and dielectric ba0.7sr0.3tio3 were epitaxially grown on a (001)-oriented nb:srtio3 substrate using pulsed laser deposition. an improved ferroelectricity with a high-temperature polarization of similar to 63.7 mu c/cm(2) at 470k was observed. the sl exhibited both dielectric and magnetic relaxation properties. two distinct dielectric relaxations were found: a carrier hopping process between fe2+ and fe3+ from 273 to 410 k and the long-range migration of oxygen vacancies from 430 to 573 k. spin-glass behavior with a freezing temperature of similar to 86.6k was also observed. this work provides a promising path forward to tailor the multiferroic properties of bfo-based structures for high-temperature applications. published under license by aip publishing. |
