Calculated magnetic exchange interactions in the van der Waals layered magnet CrSBr

Xiangyan Bo et al.

Summary: In this study, a comprehensive investigation on both bulk and monolayer CrSBr is conducted using the first-principles linear-response method. It is confirmed that the ground state of bulk CrSBr is A-type antiferromagnetic, and there are sizable intralayer exchange interactions with small magnetic frustration. The significant electron doping effect and strain effect are demonstrated, with increased Curie temperature for monolayer CrSBr and an antiferromagnetic-to-ferromagnetic phase transition for bulk CrSBr. The magnon spectra are also calculated using linear spin-wave theory. These features of CrSBr can help clarify the microscopic magnetic mechanism and promote its application in spintronics.

The Bulk van der Waals Layered Magnet CrSBr is a Quasi-1D Material

Julian Klein et al.

Summary: In this study, it was found that the magnetic semiconductor CrSBr behaves like a quasi-1D material in a magnetically ordered environment. The strong 1D electronic character of CrSBr originates from the Cr-S chains and the weak interlayer hybridization, leading to anisotropy in effective mass and dielectric screening. Moreover, CrSBr hosts spectrally narrow excitons of high binding energy and oscillator strength due to reduced dimensionality and interlayer coupling. Overall, CrSBr is an experimentally attractive candidate for the study of exotic exciton and 1D-correlated many-body physics.

Strong Spin-Phonon Coupling in Two-Dimensional Magnetic Semiconductor CrSBr

Xiaomin Xu et al.

Summary: In this work, the spin-phonon coupling effect in the two-dimensional magnetic semiconductor CrSBr is investigated using density-functional theory. It is found that the phonon vibrations are strongly influenced by the spin ordering, and the SPC constant in CrSBr is one order of magnitude larger than that in most other 2D materials. Furthermore, lattice deformation can tune the Curie temperature of the system and enhance the thermal conductivity.

Strong Neel Ordering and Luminescence Correlation in a Two-Dimensional Antiferromagnet

Yongheng Zhou et al.

Summary: Magneto-optical effect is widely used in various applications, and the discovery of 2D van der Waals layered magnets has opened up new possibilities for investigating magneto-optical phenomena. However, the low luminescence efficiency of most 2D antiferromagnets has hindered their applications. This study uncovers strong light-magnetic ordering interactions in 2D antiferromagnetic MnPS3 and demonstrates their correlation with Neel ordering using a newly-emerged near-infrared photoluminescence mode.

Magnetic Order and Symmetry in the 2D Semiconductor CrSBr

Kihong Lee et al.

Summary: The discovery of ferromagnetic ordering in monolayers of CrSBr, as well as the antiferromagnetic coupling in multilayers, highlights the unique magnetic properties of this 2D material. The Neel temperature of CrSBr increases with decreasing layer number, setting it apart from other 2D magnets. These findings introduce CrSBr as an exciting 2D magnetic semiconductor with potential applications in magnetic-electronic coupling and toroidal moments.

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.

Triaxial magnetic anisotropy in the two-dimensional ferromagnetic semiconductor CrSBr

Ke Yang et al.

Summary: The study using first-principles calculations and Monte Carlo simulations investigates the electronic structure and magnetic properties of CrSBr in bulk and monolayer forms. Bulk CrSBr is found to be a magnetic semiconductor with a triaxial magnetic anisotropy, attributed to the joint effects of spin-orbit coupling and magnetic dipole-dipole interaction. The monolayer of CrSBr shows persistent intralayer ferromagnetic exchange and a stronger contribution of shape anisotropy to the magnetic anisotropy. Monte Carlo simulations predict a Curie temperature of 175 K for the CrSBr monolayer, with the potential for further increasing the temperature by applying a uniaxial tensile or compressive strain along specific axes.
