Cholesteric Fingers from a Magnetic Perspective: Topology, Energetics, and Interactions

Takayuki Shigenaga, Andrey O. Leonov

Chiral liquid crystals and chiral magnets host a wide variety of topological solitons described by closely related continuum theories, namely the Frank-Oseen and Dzyaloshinskii mod…

Low-Temperature Skyrmions and Spiral Reorientation Processes in Chiral Magnets with Cubic Anisotropy: Guidelines for Bridging Theory and Experiment

A. O. Leonov, G. Gödecke, J. Grefe +2

We revisit the phenomenological Dzyaloshinskii framework, a central theoretical approach for describing magnetization processes in bulk chiral magnets, and demonstrate how magnetoc…

Meron-mediated phase transitions in quasi-two-dimensional chiral magnets with easy-plane anisotropy: successive transformation of the hexagonal skyrmion lattice into the square lattice and into the tilted FM state

Andrey O. Leonov

I revisit the well-known structural transition between hexagonal and square skyrmion lattices induced by increasing easy-plane anisotropy in quasi-two-dimensional chiral magnets. I…

Reorientation transition between square and hexagonal skyrmion lattices near the saturation into the homogeneous state in quasi-two-dimensional chiral magnets

Andrey O. Leonov

I revisit the well-known phase transition between the hexagonal skyrmion lattice and the homogeneous state within the phenomenological Dzyaloshinskii theory for chiral magnets whic…
