Anomalous Hall Effect in Geometrically Frustrated Magnets
Figure 4
Left: the crystal structure of Nd2Mo2O7 is made up of Mo and Nd tetrahedra. At 10 K the spin chirality of the magnetic order on the Nd tetrahedra is transferred to the Mo tetrahedra via the exchange interaction. Right: the magnetic structures of the Nd and Mo tetrahedra form antiparallel “umbrellas”. Figure taken from [3].
