Van der Waals lattice-induced colossal magnetoresistance in Cr2Ge2Te6 thin flakes [PDF]

open access: yesNature Communications, 2022
Due to their layered structure, and resulting weak interlayer exchange coupling, van der Waals materials can exhibit distinct behaviour depending on whether the spins are aligned in the plane, or perpendicular.
