Topological Hall signatures of magnetic hopfions

16 Mar 2020 Göbel Börge Akosa Collins Ashu Tatara Gen Mertig Ingrid

Magnetic hopfions are topologically protected three-dimensional solitons that are constituted by a tube which exhibits a topologically nontrivial spin texture in the cross-section profile and is closed to a torus. Here we show that the hopfion's locally uncompensated emergent field leads to a topological Hall signature, although the topological Hall effect vanishes on the global level... (read more)
