Strain-Modulated Magnetism in MoS(2)

Since the experiments found that two-dimensional (2D) materials such as single-layer MoS(2) can withstand up to 20% strain, strain-modulated magnetism has gradually become an emerging research field. However, applying strain alone is difficult to modulate the magnetism of single-layer pristine MoS(2), but applying strain combined with other tuning techniques such as introducing defects makes it easier to produce and alter the magnetism in MoS(2). Here, we summarize the recent progress of strain-dependent magnetism in MoS(2). First, we review the progress in theoretical study. Then, we compare the experimental methods of applying strain and their effects on magnetism. Specifically, we emphasize the roles played by web buckles, which induce biaxial tensile strain conveniently. Despite some progress, the study of strain-dependent MoS(2) magnetism is still in its infancy, and a few potential directions for future research are discussed at the end. Overall, a broad and in-depth understanding of strain-tunable magnetism is very necessary, which will further drive the development of spintronics, straintronics, and flexible electronics.
