First Principles Theories of Piezoelectric Materials

open access: yes, 2007
Piezoelectrics have long been studied using parameterized models fit to experimental data, starting with the work of Devonshire in 1954. Much has been learned using such approaches, but they can also miss major phenomena if the materials properties are ...

Magnetoelectric coupling of domains, domain walls and vortices in a multiferroic with independent magnetic and electric order

open access: yesNature Communications, 2021
Magnetically induced ferroelectrics exhibit rigidly coupled magnetic and electric order. The ordering temperatures and spontaneous polarization of these multiferroics are notoriously low, however.

Flexomagnetoelectric effect in bismuth ferrite

open access: yes, 2008
There is a profound analogy between inhomogeneous magnetoelectric effect in multiferroics and flexoelectric effect in liquid crystals. This similarity gives rise to the flexomagnetoelectric polarization induced by spin modulation.

Perspective on 2D perovskite ferroelectrics and multiferroics [PDF]

open access: yesAppl. Phys. Lett. 125, 230503 (2024)
Two-dimensional (2D) ferroelectrics and multiferroics have attracted considerable scientific and technological interest in recent years due to the increasing demands for miniaturization and low energy consumption of electronic devices. At present, the research on 2D ferroelectrics and multiferroics is still focused on van der Waals materials, while the

Layer-Selective Non-Reciprocal Electric-Field Switching of Magnetism in van der Waals Heterostructure Multiferroics [PDF]

open access: yesarXiv, 2023
Multiferroic materials provide robust and efficient routes for the control of magnetism by electric fields, which has been diligently sought after for a long time. The two-dimensional (2D) vdW multiferroics is a more exciting endeavour. To date, the nonvolatile manipulation of magnetism through ferroelectric polarization still remains challenging in a ...

The properties of isolated chiral skyrmions in thin magnetic films

open access: yesNew Journal of Physics, 2016
Axisymmetric solitonic states ( chiral skyrmions ) were first predicted theoretically more than two decades ago. However, until recently they have been observed in a form of skyrmionic condensates (hexagonal lattices and other mesophases).
