2024年8月12日 · CrSBr is a fascinating exemplar: a semiconducting A-type layered antiferromagnet that can be exfoliated down to a ferromagnetic monolayer limit 1, it demonstrates strong exciton-phonon coupling...

This work provides strategies for controllably inducing defects and magnetic properties in CrSBr, demonstrates RRS as a sensitive probe for detecting defects, dopants, or disorder that breaks crystal symmetry and their related spin-phonon coupling, and underpins CrSBr as an ideal candidate material with potential to study defect engineered ...

2021年4月15日 · In multilayers, the ferromagnetic monolayers are coupled antiferromagnetically, and in contrast to other 2D magnets, the Néel temperature of CrSBr increases with decreasing layer number. We identify magnetic dipole and magnetic toroidal moments as order parameters of the ferromagnetic monolayer and antiferromagnetic bilayer, respectively.

2023年9月5日 · Resonant Raman scattering is used to reveal distinct vibrational defect signatures. In pristine CrSBr, it is shown that bromine atoms mediate vibrational interlayer coupling, allowing for distinguishing between surface and bulk defect modes.

We discuss the stability of CrSBr in air and show atomic scale structural manipulation through electron beam‐driven transformations. We conclude that the stability and structural amenability of CrSBr provide opportunities for imagining devices that use bulk crystals yet exploit unique magnetic and quantum confinement efects.

Herein, we investigate the magnetic properties, magnon dispersion, and spin dynamics of the air-stable 2D magnetic semiconductor CrSBr (T C = 146 K) under mechanical strain using first-principles calculations. Our results provide a deep microscopic analysis of the competing interactions that stabilize the long-range ferromagnetic order in the ...
