  • When two magnetic layers are separated by a metallic spacer, an interlayer exchange coupling can occur. Recently, it has been shown that interlayer Dzyaloshinskii-Moriya interactions can also occur, driving chiral spin canting in the magnetic layers. Here, Arregi et al. demonstrate a large interlayer Dzyaloshinskii-Moriya interaction in Co/Ag/Co multilayers, which occurs despite the weak atomic spin-orbit coupling of the Ag spacer layer.

  • The anticipated role of skyrmions as information carriers in spintronic devices has, so far, been hampered by difficulties in controlling their motion. Here, the authors use micromagnetic simulations to investigate the temperature-dependent motion of skyrmions, revealing that their magnetic texture reacts on two different time scales.

  • When skyrmions are travelling along a given path their motion is impaired by the skyrmion Hall effect which causes them to veer towards the edges of their track rather than to continue in a linear direction. To help counteract this issue, the authors investigate skyrmion edge interactions demonstrating that a ferromagnetic Co/Fe rim adjacent to the Pd/Fe bilayer on Ir(111) can prevent skyrmion annihilation at the film edge and also stabilizes zero-field skyrmions.
