Controlling skyrmion bubble confinement by dipolar interactions [PDF]

, 2019
Large skyrmion bubbles in confined geometries of various sizes and shapes are investigated, typically in the range of several micrometers. Two fundamentally different cases are studied to address the role of dipole-dipole interactions: (I) when there is ...
