DOI: 10.1016/j.matlet.2020.128447

Abstract: Abstract Ca3Ti2O7 with Ruddlesden-Popper structure is a typical hybrid improper ferroelectric with large polarization. But the room-temperature ferroelectricity of Ca3Ti2O7 ceramics prepared by a solid-state method is not good enough. In this work, Ca3Ti2O7 ceramics… read more here.

DOI: 10.1038/s41467-019-13474-x

Abstract: The secondary nature of polarization in improper ferroelectrics promotes functional properties beyond those of conventional ferroelectrics. In technologically relevant ultrathin films, however, the improper ferroelectric behavior remains largely unexplored. Here, we probe the emergence of… read more here.

DOI: 10.1063/1.5001956

Abstract: Hybrid improper ferroelectricity (HIF) has been proposed as a candidate approach to create room-temperature multiferroic materials with an intrinsic electric-field controlled magnetism effect, and HIFs in bi-layered Ruddlesden-Popper Ca3-xSrxTi2O7 ceramics have been confirmed in the… read more here.

DOI: 10.1063/1.5003877

Abstract: The hybrid improper ferroelectricity Ca3Mn2O7 (CMO) has been a subject of remarkable interest due to potential multiferroicity. In this paper we synthesized CMO and Ca2.94Na0.06Mn2O7 (CNMO) ceramics and investigated their structural and magnetic properties. It… read more here.
