Magnetoelectricity in multiferroics: a theoretical perspective
National Science Review, 2019 ABSTRACTThe key physical property of multiferroic materials is the existence of coupling between magnetism and polarization, i.e. magnetoelectricity. The origin and manifestations of magnetoelectricity can be very different in the available plethora of multiferroic systems, with multiple possible mechanisms hidden behind the phenomena.

Electromagnons in Multiferroic Materials [PDF]
, 2008 This dissertation focuses on the study of spin-lattice and magnon-phonon coupling in multiferroic materials based on their electrodynamic response. Based on a study of the electrodynamic response in the far infrared region of the electromagnetic spectrum

Multiferroics: different routes to magnetoelectric coupling
npj SpintronicsAbstract The simultaneous presence of ferroelectricity and magnetism in multiferroics breaks both spatial inversion and time reversal symmetries at the macroscopic scale, which opens the door to many interesting phenomena and resembles the violation of these symmetries in particle physics.

Experimental investigations on multiferroic materials [PDF]
, 2019 By definition, a single phase multiferroic is a material that simultaneously possesses two or more so-called ferroic order parameters such as ferroelectricity, ferromagnetism and ferroelasticity.

Giant Direct Magnetoelectric Effect in Nanocomposite CoFe2O4:PVDF‐TrFE Thin Films
Advanced Science, EarlyView.A novel three‐step grow‐etch‐fill fabrication approach creates structured cobalt ferrite/ferroelectric polymer nanocomposites with high interfacial areas. Driven by efficient strain‐mediated coupling, this crystalline system achieves a giant room‐temperature magnetoelectric coefficient nearly two orders of magnitude higher than other CFO/PVDF‐TrFE thin

Advanced Science, EarlyView.A reversible five‐phase topological cycle is achieved in a minimalist cobalt formate metal–organic framework. The amorphous phase functions as a programmable reactive hub, selectively reconstructing into four distinct crystalline architectures through cationic templates, humidity, or CO2.
