push_pin When Bloch point hops through magnetic multilayers

October 27, 2021

In this Letter, we theoretically demonstrate the annihilation of single skyrmions in a multilayer structure. The process is mediated by topological hedgehog singularities known as Bloch points, whose intralayer and interlayer dynamics gives rise to intriguing emergent electromagnetic fields …

Surface roughness helps to stabilise out-of-plane spin textures in an uniformly in-plane magnetised system

November 13, 2020

We developed a surface roughness model for magnetic systems, by taking into account the space-dependent uniaxial anisotropy and Dzyaloshinskii-Moriya interaction (DMI) …
