Skyrmion tilting by a transport current self-field

Skyrmions are known to be weakly coupled to the crystalline directions in the host material and in particular they will closely follow the direction of the applied magnetic field. Here we report on small-angle neutron scattering (SANS) studies of the skyrmion lattice (SkL) in circular MnSi crystal in the presence of a radial electric current. Here, the magnetic self-field generated by the current is perpendicular to both the current direction and the applied magnetic field. Despite being orders of magnitude smaller than the applied field, the self-field causes a tilting of the SkL which can be observed by SANS. In my talk I will discuss these effects and provide a quantitative comparison between the self-field and SkL tilting angle.
