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.
