TLDR
The detection of a magnetoelectric effect is reported that is visible in electron paramagnetic resonance absorption of molecular helices under electric field modulation and confirmed by specific symmetry properties and spectral simulation.Abstract:
The possibility to operate on magnetic materials through the application of electric rather than magnetic fields—promising faster, more compact and energy efficient circuits—continues to spur the investigation of magnetoelectric effects. Symmetry considerations, in particular the lack of an inversion centre, characterize the magnetoelectric effect. In addition, spin–orbit coupling is generally considered necessary to make a spin system sensitive to a charge distribution. However, a magnetoelectric effect not relying on spin–orbit coupling is appealing for spin-based quantum technologies. Here, we report the detection of a magnetoelectric effect that we attribute to an electric field modulation of the magnetic exchange interaction without atomic displacement. The effect is visible in electron paramagnetic resonance absorption of molecular helices under electric field modulation and confirmed by specific symmetry properties and spectral simulation. A modulation of the magnetic exchange interaction using an electric field, in the absence of atomic displacement and not relying on spin–orbit coupling, is reported.read more

The Renaissance of Magnetoelectric Multiferroics
Nicola A. Spaldin,Manfred Fiebig +1 more
TL;DR: Magnetoelectric multiferroics combine ferromagnetic magnetization and ferroelectricity in the same phase and have tremendous potential for applications, not only because they possess the properties of both parent phenomena, but also because coupling between ferromagnetism and electric polarization can lead to additional novel effects as discussed by the authors.

Classifying multiferroics: Mechanisms and effects
TL;DR: In this article, it was shown that strong cross-coupling of responses exist in solids (i.e., the appearance of magnetization M in an electric field E, or the inverse effect of electric polarization P generated by the application of magnetic field H), and that there may exist systems in which two types of ordering ((ferro)magnetism, the spontaneous order) could exist.
