Abstract

Topologically non-trivial spin textures, such as skyrmions and dislocations, display emergent electrodynamics and can be moved by spin currents over macroscopic distances. These unique properties and their nanoscale size make them excellent candidates for the development of next-generation logic gates, race-track memory, and artificial synapses for neuromorphic computing. A major challenge for these applications - and the investigation of nanoscale magnetic structures in general - is the realization of adequate detection schemes that provide the required resolution and sensitivity. Here, the local magnetic properties of topological defects in FeGe are studied, revealing a pronounced non-linear response that distinguishes the individual spin textures from the helimagnetic background. Combining magnetic force microscopy and micromagnetic simulations, the non-linear response is linked to the local magnetic susceptibility, representing an innovative approach for detecting topologically non-trivial spin textures and domain walls. Based on the findings, a read-out scheme is proposed using planar micro-coils compatible with semiconductor fabrication methods, facilitating the transfer to spintronics devices.
