Some current problems in perovskite nano-ferroelectrics and multiferroics: kinetically-limited systems of finite lateral size [PDF]

open access: yesScience and Technology of Advanced Materials, 2015
We describe some unsolved problems of current interest; these involve quantum critical points in ferroelectrics and problems which are not amenable to the usual density functional theory, nor to classical Landau free energy approaches (they are ...

Proposing Altermagnetic‐Ferroelectric Type‐III Multiferroics with Robust Magnetoelectric Coupling [PDF]

open access: hybridAdvanced Materials, EarlyView.
Multiferroics are highly sought after for advanced technological applications. Here, a novel class of type‐III multiferroics is proposed, where ferroelectricity and altermagnetism are inherently interlocked by crystal symmetry, setting them apart from conventional multiferroics. The ferroelectric switching is shown to fully invert the spin polarization

Ferroelectricity coexisted with p-orbital ferromagnetism and metallicity in two-dimensional metal oxynitrides

open access: yesnpj Computational Materials, 2022
Two-dimensional (2D) multiferroics have attracted increasing interests in basic science and technological fields in recent years. However, most reported 2D magnetic ferroelectrics are based on the d-electron magnetism, which makes them rather rare due to

Control of magnetic transitions via interlayer engineering in ferroelectric H2O–OH systems [PDF]

open access: yesNature Communications
Controlling magnetic phase transitions in two-dimensional (2D) multiferroics is crucial for both fundamental scientific knowledge and practical applications. Here, we present a general strategy for inducing magnetic transitions in 2D ferroelectrics based

Polar magnetic oxides from chemical ordering: A new class of multiferroics

open access: yesAPL Materials, 2020
Combining ferroelectricity and magnetism in the same material remains a challenge because it involves complex crystal chemistry and stringent symmetry requirements. In conventional ferroelectrics, the polarization arises from the second-order Jahn–Teller

Electrocaloric effects in ferroelectrics and multiferroics from first principles

open access: goldJournal of Materiomics
The electrocaloric (EC) effect characterizes the change in temperature or entropy of a material under the application of an external electric field. Ferroelectric and multiferroic materials have attracted considerable interest due to their potential for ...
