“…The domain walls may be charged or polarized [457], as seen under scanning SET [451]. (Readers are referred to the recent review by Salje et al [60] for studies on the details of the twin walls.) Domain walls may attract defects such as oxygen vacancies (predicted for CaTiO 3 [154]).…”

“…We note that polar domain walls in nonferroelectric structures, e.g. Néel-like domain walls in iron garnet films [206], ferroelastic domain boundaries [207][208][209] have also been reported. All of this holds potential for magnetoelectric coupling in heterostructures right at the wall location in a non-magnetoelectric host compound.…”

For next-generation technology, magnetic systems are of interest due to the natural ability to store information and, through spin transport, propagate this information for logic functions. Controlling the magnetization state through currents has proven energy inefficient. Multiferroic thin-film heterostructures, combining ferroelectric and ferromagnetic orders, hold promise for energy efficient electronics. The electric field control of magnetic order is expected to reduce energy dissipation by 2–3 orders of magnitude relative to the current state-of-the-art. The coupling between electrical and magnetic orders in multiferroic and magnetoelectric thin-film heterostructures relies on interfacial coupling though magnetic exchange or mechanical strain and the correlation between domains in adjacent functional ferroic layers. We review the recent developments in electrical control of magnetism through artificial magnetoelectric heterostructures, domain imprint, emergent physics and device paradigms for magnetoelectric logic, neuromorphic devices, and hybrid magnetoelectric/spin-current-based applications. Finally, we conclude with a discussion of experiments that probe the crucial dynamics of the magnetoelectric switching and optical tuning of ferroelectric states towards all-optical control of magnetoelectric switching events.

“…Multiferroic materials [1][2][3] may exhibit a wide variety of unique behaviors due to an interplay between two or more ferroic orderings that appear in the same temperature range. An obvious example of such an interplay is the effect of magnetic shape memory (MSM), which appears in ferromagnetic shape memory alloys (FSMAs), [4][5][6][7] and is manifested as magnetically induced martensite transformation (MIM) or magnetically induced reorientation of martensite (MIR).…”

This review summarizes recent advances in first‐principles simulations of the structural, mechanical, and magnetomechanical properties of Ni–Mn–Ga‐based ferromagnetic shape memory alloys from the perspective of experimental characterization. It focuses on calculations that can capture the main features of the low‐temperature phases, particularly the appearance of spatial modulations, the occurrence of intermartensitic transitions, and the high mobility of the twin boundaries, which allows for magnetically induced reorientation. Although the calculations can only be used to interpret some of these features and are not yet ready to be used as a tool for designing new alloys with the required properties, the gap between experimental observations and simulations is narrowing. When experiments and theory are discussed together, new challenges arise for both. In addition, new results on first‐principles‐determined elastic constants of the 10M martensite of Ni–Mn–Ga are presented and discussed with respect to the high mobility of the twin boundaries.
