Abstract

Recent experimental and theoretical work has focused on two-dimensional van der Waals(2D vdW)mag-nets due to their potential applications in sensing and spintronics devises.In measurements of these emerging materials,conventional magnetometry often encounters challenges in characterizing the magnetic properties of small-sized vdW materials,especially for antiferromagnets with nearly compensated magnetic moments.Here,we investigate the magnetism of 2D antiferromagnet CrPS4 with a thickness of 8 nm by using dynamic cantilever magnetometry(DCM).Through a combination of DCM experiment and the calculation based on a Stoner-Wohlfarth-type model,we unravel the magnetization states in 2D CrPS4 antiferromagnet.In the case of H||c,a two-stage phase transition is observed.For H 上 c,a hump in the effective magnetic restoring force is noted,which implies the presence of spin reorientation as temperature increases.These results demonstrate the benefits of DCM for studying magnetism of 2D magnets.
