Emerging properties of van der Waals (vdW) materials at two-dimensional (2D) limit have been broadening their varieties, ranging from spin-orbit coupled transport properties, valley-polarized luminescence, spin-valley-locked superconductivities, to topological quantum transport. As one of big advantages of 2D materials, 2D physical phenomena could be more and more enriched by integrating different 2D materials into a heterostructure, so-called vdW heterostructures, providing a new high-quality platform for 2D physics. Here we created new magnetic vdW heterostructures with NbSe₂ and 2D ferromagnet, vanadium selenide epitaxial thin film. As a result, Zeeman-type spin orbit coupling, which is unique to the some vdW materials such as NbSe₂, was found to modulate the magnetic anisotropy dramatically. In the presentation, we will discuss the details of magnetic modulation in those heterostructures and the extended types of heterointerfaces.
