Abstract
- We investigate the micromechanical exfoliation and van der Waals (vdW) assembly of ferromagnetic layered dichalcogenide Fe<subscript>0.25</subscript>TaS<subscript>2</subscript>. The vdW interlayer coupling at the Fe-intercalated plane of Fe<subscript>0.25</subscript>TaS<subscript>2</subscript> allows exfoliation of flakes. A vdW junction between the cleaved crystal surfaces is constructed by dry transfer method. We observe tunnel magnetoresistance in the resulting junction under an external magnetic field applied perpendicular to the plane, demonstrating spin-polarized tunneling between the ferromagnetic layered material and the vdW junction.
