Zoology of skyrmions and the role of magnetic anisotropy in the stability of skyrmions — •Istvan Kezsmarki1, Sandor Bordacs1, Jonathan White2, Vladimir Tsurkan3, Alois Loidl3, Peter Milde4, Hiroyuki Nakamura5, and Andrey Leonov6 — 1Budapest University of Technology and Economics, Budapest, Hungary — 2Paul Scherrer Institute, Villingen, Switzerland — 3University of Augsburg, Augsburg, Germany — 4Technical University of Dresden, Dresden, Germany — 5University of Kyoto, Kyoto, Japan — 6University of Hiroshima, Hiroshima, Japan
Skyrmions are nanometric magnetic objects with high stability owing to their topological structures. The internal spin pattern of skyrmions depends on the crystal symmetry of the host materials. While we know many chiral crystals hosting Bloch-type skyrmions, Néel-type skyrmions have only recently observed in polar compounds. On experimental basis, I am going to compare the main characteristics of the two types of skyrmions and discuss the effect of magnetic anisotropy on the thermal stability range of the corresponding Bloch- and Néel-type skyrmion lattices.
