Unfolding of Vortices into Topological Stripes in a Multiferroic Material
Unfolding of Vortices into Topological Stripes in a Multiferroic Material
Multiferroic hexagonal $R{\mathrm{MnO}}_{3}$ ($R=\text{rare}\text{ }\text{earths}$) crystals exhibit dense networks of vortex lines at which six domain walls merge. While the domain walls can be readily moved with an applied electric field, the vortex cores so far have been impossible to control. Our experiments demonstrate that shear strain induces a Magnus-type …
