Magnetic skyrmion interactions in the micromagnetic framework
Richard Brearton, Gerrit van der Laan, Thorsten Hesjedal
Magnetic skyrmions are localized swirls of magnetization with a non-trivial topological winding number. This winding increases their robustness to superparamagnetism and gives rise…

Resonant x-ray diffraction from chiral electric-polarization structures
Stephen W. Lovesey, Gerrit van der Laan
Heterostructures of PbTiO/SrTiO superlattices have shown the formation of "polar vortices", in which a continuous rotation of ferroelectric polarization spontaneously forms…
