Degenerate antiferromagnetic states in spinel oxide LiV2O4 |
Four different spin configurations of LiV2O4 in a 1×1×1 cubic cell: (a) DT AFM state, namely, the ferromagnetic V4 tetrahedral clusters connecting each other with the corner-sharing AFM V4 tetrahedra, (b) AFM1, (c) AFM2, and (d) AFM3 states. Here, the green, red, pink, and blue balls denote the Li, O, spin-up V, and spin-down V atoms, respectively. |
