Magnetism in curved VSe₂ monolayers.

ABSTRACT: Our extensive first-principles calculations on magnetic VSe₂ monolayers reveal the curvature-induced periodic fluctuation in the magnetic moments of V atoms and the occurrence of charge density waves for curved VSe₂ monolayers. The bending energies of curved 2H-VSe₂ monolayers increase with increasing curvature but that of curved 1T-VSe₂ monolayers with curvature is not monotonic. The significant periodic magnetic orders in curved VSe₂ monolayers can be attributed to the curvature-induced modification of V-Se bond structure and periodic length variations in V-Se bonds. A phenomenological model is established to describe the relation of the total magnetic moment in one period of a curved VSe₂ monolayer with its curvature radi
