Description
In the radial setting, we analyze how magnetic skyrmions transition to (large scale) bubbles in the entire regime of positive energetic cost of domain walls, i.e., far away from the conformal limit. First, we demonstrate existence of radial, skyrmionic bubbles throughout this maximal regime of energetic feasibility. Second, we perform a Gamma-convergence analysis in the limit of vanishing domain wall energy and establish the precise leading order size and domain wall profile of the expanding bubbles.
This is joint work with Cyrill Muratov and Valeriy Slastikov.
