Coupled ferroelectricity
WebWe define the “ferroelectric anisotropy” (FEA) as the energy required to modify the direction (as well as size) of the polarization by switching the crystal symmetry between different CO phases (in this case COII and COIII); the FEA may find useful applications in future devices, such as multiple-state memories where the information can be stored … Web2D intercorrelated ferroelectrics, exhibiting a coupled in-plane and out-of-plane ferroelectricity, is a fundamental phenomenon in the field of condensed-mater physics. The current research is based on the …

Web摘要： We present a first-principles investigation of ferroelectricity in layered perovskite oxide La 2 Ti 2 O 7 (LTO). Our calculations indicate that LTO's high-temperature (1770 K) ferroelectric transition results from the condensation of two soft modes that have the same symmetry and are strongly coupled anharmonically. Webferroelectricity, AFM, and QAHE. Importantly, through rational van der Waals sliding, these exotic properties are strongly coupled. Such coupling could demonstrate many distinctive physics, for example, ferroelectric control of itinerant AFM phase and the sign of quantized anomalous Hall plateau.
