The discovery of two-dimensional (2D) van der Waals magnets has opened a new frontier in material science and condensed matter physics, paving a way for exploring2D magnetism and its promising applications in spintronics, quantum computing, and beyond. In particular, the unique layered structure of the van der Waals magnets facilitates the control of precise atomic layers, tunable magnetism, and high magnetic anisotropy, providing a novel platform for spin-related devices previously unattainable with three-dimensional (3D) bulk counterparts.  

In this talk, I will introduce the 2D layered antiferromagnet CrSBr and its novel approach on device application. First, I will present the observation of localized superconducting magnetoresistance, made possible by leveraging the high magnetic anisotropy of CrSBr [1]. Second, I will showcase the nonvolatile electrical control of antiferromagnetic properties in CrSBr, achieved by exploiting its metamagnetic transition [2].
