  We investigate the micromechanical exfoliation and van der Waals (vdW)
assembly of ferromagnetic layered dichalcogenide Fe0.25TaS2. The vdW interlayer
coupling at the Fe-intercalated plane of Fe0.25TaS2 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 through the vdW junction.
