Deformation of a Néel-type Skyrmion in a Weak Inhomogeneous Magnetic Field: Magnetization Ansatz and Interaction with a Pearl Vortex

S. S. Apostoloff, E. S. Andriyakhina, I. S. Burmistrov

In this work, we develop a theory of (meta)stable states of Néel-type skyrmions in weak nonuniform magnetic fields. We claim an Ansatz for modeling the non-symmetric magnetization…
