Abstract
Micromagnetic simulations are used to investigate different strategies for tunnel magnetoresistance detection of the Néel skyrmion core direction and Bloch skyrmion chirality. When a Néel skyrmion passes beneath a perpendicularly magnetized dot separated by a tunnel barrier, a peak or dip in the tunnel magnetoresistance as a function of time reveals the core direction. When a Bloch skyrmion travels below a synthetic antiferromagnet, magnetized in-plane with an axis perpendicular to that of the track, the tunnel magnetoresistance as a function of time shows a peak followed by a dip, or vice versa, depending on the chirality. The results are compared with existing detection methods based on the Hall resistance.
