摘 要：Magnetic materials could realize the intriguing quantum anomalous Hall effect and metal-to-insulator transition when combined with band topology or electronic correlation,which have broad prospects in quantum information,spintronics,and ***,we propose the approach of designing novel two-dimensional(2D)magnetic states via d-orbital-based superatomic ***,we chose triangular zirconium dichloride disks as superatoms to construct the honeycomb superatomic *** first-principles calculations,we identified a series of 2D magnetic states with varying sizes of *** found the non-uniform stoichiometries and geometric effect of superatomic lattice give rise to spin-polarized charges arranged in different magnetic configurations,containing ferromagnetic coloring triangles,antiferromagnetic honeycomb,and ferromagnetic kagome ***,these magnetic states are endowed with nontrivial band topology or strong correlation,forming an ideal Chern insulator or antiferromagnetic Dirac Mott *** work not only reveals the potential of d-orbital-based superatoms for generating unusual magnetic configurations,but also supplies a new avenue for material engineering at the nanoscale.
