We report unidirectional charge transport in a $\mathrm{NbSe_2}$ noncentrosymmetric superconductor, which is exchange-coupled with a $\mathrm{CrPS_4}$ van der Waals layered antiferromagnetic insulator. The $\mathrm{NbSe_2/CrPS_4}$ bilayer…
We show that anisotropic energy of a 2D antiferromagnet is greatly enhanced via stacking on a magnetic substrate layer, arising from the sublattice-dependent interlayer magnetic interaction that defines an effective anisotropic energy.…
Exfoliated magnetic 2D materials enable versatile tuning of magnetization, e.g., by gating or providing proximity-induced exchange interaction. However, their electronic band structure after exfoliation has not been probed, most likely due…

Direction-dependent charge transport and optical responses are characteristic of van der Waals (vdW) materials with strong in-plane anisotropy. While transition-metal trichalcogenides (TMTCs) exemplify this behavior, heavier analogs remain…
