Abstract
The coupling of spin and charge in magnetic semiconductors lies at the heart of the field of spintronics and has attracted significant interest for new computing technologies. In this paper, we will review our recent progress in studying and controlling magneto-exciton coupling in the layered antiferromagnetic semiconductor CrSBr. The anisotropic Wannier-type excitons in this material serve as a sensor of the interlayer magnetic coupling. Using this exciton sensor, we found that the magnetic order is extremely tunable by the application of tensile strain, with a reversible AFM to FM transition occurring at large but experimentally feasible strains. These results establish CrSBr as an exciting platform for harnessing spin-charge-lattice coupling to the 2D limit.
