Axisymmetric magnetic whirling cylinders of nanometre sizes, embedded into a magnetically saturated state (magnetic skyrmions) become a hot topic during the past decade. They are considered as promising candidates for highly mobile, low-power, and super-dense magnetic data storage and many other spintronic applications.
Magnetic skyrmions belong to a special class of “self-supporting” particle-like objects known as “solitons”. The discovery of solitons as intrinsically stable, localized states in the middle of the last century is known as the “soliton revolution” which introduced a new physical paradigm: a ‘solid’ particle-like object can be induced in continuous media and easily controlled and manipulated by external forces (the term “soliton” was coined by Martin Kruskal and Norman Zabusky in 1969). By now, solitons (including different types of skyrmions) have been discovered in many condensed matter systems.
This section collects the materials of the Meetings highlighting the basic properties and physical foundations of skyrmions and othe solitonic states in different condensed matter systems including noncentrosymmetric anti- and ferromagnets, magnetic systems with competing exchange interactions, chiral liquid crystals, ferroelectrics, and mulitferroics.
