Abstract Abundant chemical diversity and structural tunability make organic–inorganic hybrid perovskites (OIHPs) a rich ore for ferroelectrics. However, compared with their inorganic counterparts such as BaTiO 3 , ferroelectric key properties, including large spontaneous polarization ( P s ), low coercive field E c strong second harmonic generation (SHG) response, have long been great challenges, which hinder commercial applications. Here, quasi-one-dimensional OIHP DMAGeI (DMA =...
Owing to the strong spin-orbit coupling and related fascinating physical properties, heavy 5d transition-metals exhibit desirable application prospects. However, up now, magnetic materials are still very limited, especially rare for tungsten. In this work, we theoretically predict a two-dimensional multiferroic W3Cl8 monolayer. Intrinsic magnetism of tungsten is activated by W ions' fractional valence in breathing Kagome lattice reduced effective dimension. A coplanar Y-type...

With the development of two-dimensional (2D) magnetic materials, magneto-optical Kerr effect (MOKE) is widely used to measure ferromagnetism in 2D systems. Although this usually inactive antiferromagnets (AFM), recent theoretical studies have demonstrated that presence MOKE relies on symmetry system and with noncollinear order can also induce a significant signal even without net magnetization. However, phenomenon rarely studied systems due scarcity appropriate materials hosting AFM order....

van der Waals magnetic heterostructures, consisting of a wide band-gap nitride semiconductor and an intrinsic ferromagnetic semiconductor, are potentially useful for low-dimensional spintronic field-effect transistors. However, there is significant challenge. For instance, the integration often leads to decreased Curie temperature, anisotropy direction change, low conductivities. Here, we employ first-principles density-functional method systematically investigate electronic properties...
The lacking of two-dimensional intrinsic room-temperature ferromagnetic semiconductors severely restricts the development future low-dimensional semiconductor spintronic devices. Is it possible to indirectly obtain that work at room temperature from available antiferromagnetic metal through quantum state regulation?

Electric field control of magnetism in solids, i.e. the converse magnetoelectricity, is highly desired for applications scalable energy-efficient logic devices. However, it not only a technical challenge but also scientific paradox, since principle electric and magnetic degrees freedom obey distinct rules symmetries. Despite great progresses obtained community multiferroics during past decades, success magnetoelectricity remains on its way more alternative approaches with conceptual...

At present, researchers have proved several kinds three-dimensional altermagnets, but research on two-dimensional (2D) altermagnets remains elusive. Here, we propose method for designing altermagnetism in 2D lattices: bilayer reversed stacking. This could enable altermagnetism-type spin splitting to occur intrinsically the spin-splitting can...
