Hopfions are an intriguing class of string-like solitons, named according to a classical topological concept classifying three-dimensional direction fields. The search for hopfions in real physical systems has been ongoing for nearly half a century,

We focus on a special type of domain walls appearing in the Landau-Lifshitz theory for soft ferromagnetic films. These domain walls are divergence-free $S^2$-valued transition layers that connect two directions in $S^2$ (differing by an angle $2\thet

We study the Landau-Lifshitz model for the energy of multi-scale transition layers -- called "domain walls" -- in soft ferromagnetic films. Domain walls separate domains of constant magnetization vectors $m^\pm \in \mathbb{S}^2$ that differ by an ang

In this paper, we address the structure and interaction of neighboring asymmetric N\'eel and Bloch walls in soft ferromagnetic films. First, we review a recent reduced model for the structure of parallel systems of asymmetric walls with potentially i

We examine lower order perturbations of the harmonic map problem from $$\mathbb {R}^2$$ to $$\mathbb {S}^2$$ including chiral interaction in form of a helicity term that prefers modulation, and a potential term that enables decay to a uniform backgro

This note is about the prediction of the domain and wall configuration formed by the magnetization m in a soft ferromagnetic film under an external field. We propose a modification of the reduced model introduced by DeSimone et al. (2001), that is a
