topological Hall effect

Observing the topological Hall effect in the heterostructure of "the magnetic insulating layer with non-coplanar spin texture" and "the paramagnetic metallic layer", such as the Dy₂Ti₂O₇/Bi₂Rh₂O₇ and the DyFeO₃/CaRuO₃ heterostructure, has demonstrated the propagation of the emergent field through the interface. In this study, for the paramagnetic metallic layer, we pay attention to the two-dimensional electron with low carrier density and high mobility in the LaAlO₃/SrTiO₃ interface. We try to enhance the topological Hall effect by combining it with the magnetic insulating layer DyFeO₃.
