Prof. A. N. Bogdanov (IFW Dresden):

Magnetic properties of skyrmions in chiral ferromagnets

I overview magnetic properties of isolated and embedded skyrmions arising in bulk and confined magnetic materials with intrinsic and induced chirality. The talk consists of three parts: I. Introduction into physics of chiral skyrmions: rigorous solutions and physical properties [1,2]. II. Chiral modulations in the precursor states of cubic helimagnets. Resolving the A-phase mystery [3]. III. Skyrmions and helicoids in thin layers of chiral magnets [2,4,5]. [1] A. Bogdanov, A. Hubert. JMMM 138, 255 (1994); 195, 182 (1999). [2] M. N.
