Abstract

Antiferromagnetic materials have emerged as promising platforms for magnonic devices with lower power consumption and faster operation speed. The antiferromagnet/ferromagnet with perpendicular magnetic anisotropy is an essential heterostructure for realizing vertically polarized magnon excitation, detection, and modulation. However, it is still a significant challenge to advance this innovation. We have successfully fabricated two-dimensional antiferromagnet TMPS 3 (MnPS 3 and NiPS 3 )/Co 40 Fe 40 B 20 ferromagnet heterostructures with robust perpendicular magnetic anisotropy. We experimentally observed a magnetic anisotropy transition from the in-plane to out-of-plane easy axis by incorporating a two-dimensional MnPS 3 or NiPS 3 underlayer. This phenomenon is mainly attributed to the Fe-TMPS 3 orbital hybridization at the interface, which enhances the perpendicular magnetic anisotropy contribution from d z 2 and d yz orbital coupling, while simultaneously reducing the in-plane magnetic anisotropy contribution from d xy and d x 2– y 2 orbital coupling. Our work provides a feasible pathway for developing novel magnonic devices involving vertically or tilted polarized magnons.
