Layer-Dependent Interlayer Antiferromagnetic Spin Reorientation in Air-Stable Semiconductor CrSBr

Chen Ye et al.

Summary: In this study, we use magnetotransport characterization and first-principles calculations to reveal the layer-dependent interlayer antiferromagnetic spin reorientation in air-stable semiconductor CrSBr. We discover an odd-even layer effect of interlayer spin reorientation and identify the competitions among different factors. A layer-dependent magnetic phase diagram is also constructed.

One-dimensional Luttinger liquids in a two-dimensional moire lattice

Pengjie Wang et al.

Summary: In this study, 2D arrays of 1D Luttinger liquids (LLs) with crystalline quality were realized in twisted bilayer tungsten ditelluride (tWTe(2)). The nanoscale distance between parallel 1D electronic channels in the moire pattern of tWTe(2) is tunable by the interlayer twist angle, resulting in a large transport anisotropy. The observed power-law scaling behavior suggests the formation of a 2D anisotropic phase resembling an array of LLs.

Coupling between magnetic order and charge transport in a two-dimensional magnetic semiconductor

Evan J. Telford et al.

Summary: Tunable electron transport is demonstrated within the magnetic phase of the 2D semiconductor CrSBr, revealing a strong coupling between its magnetic order and charge transport. The magnetoresistance can be dynamically and reversibly tuned by varying the carrier concentration, providing a mechanism for controlling charge transport in 2D magnets.

Direct visualization of magnetic domains and moire magnetism in twisted 2D magnets

Tiancheng Song et al.

Summary: By studying the magnetic properties of twisted CrI3 materials, emerging magnetic textures and periodic patterns were discovered, confirming the existence of moire superlattices and exploring the coexistence of antiferromagnetic and ferromagnetic domains at different layer thicknesses. This highlights magnetic moire superlattices as a potential platform for exploring nanomagnetism.

Interlayer electronic coupling on demand in a 2D magnetic semiconductor

Nathan P. Wilson et al.

Summary: Interlayer hybridization in 2D van der Waals materials can change their properties, such as the coupling in CrSBr which can be changed by switching the magnetic order. The stacking of monolayers of 2D materials can introduce new properties, like moire bands and highly correlated electronic states.
