Three-dimensional structure of hybrid magnetic skyrmions determined by neutron scattering

Magnetic skyrmions are topologically protected chiral spin textures which present opportunities for next-generation magnetic data storage and logic information technologies. The topology of these structures originates in the geometric configuration spins - more generally described as structure. While skyrmion structure is most often depicted using a 2D projection three-dimensional structure, recent works have emphasized role all three dimensions determining their response to external stimuli. In this work, grazing-incidence small-angle neutron scattering polarized reflectometry used determine hybrid skyrmions. skyrmions, includes combination N\'eel-like Bloch-like components along length, expected significantly contribute notable stability, ambient conditions. To interpret data, micromagnetic simulations were performed, corresponding diffraction patterns determined Born approximation transformation. converged profile reveals with depth profile, including thickness Bloch N\'eel segments diameter core.
