“…[1][2][3] Skyrmion states were predicted to appear in ultrathin films [4][5][6] and their observation in a variety of physical systems [7][8][9][10][11][12][13][14] has led to intense efforts to understand the physical conditions under which they are stable, along with their static and dynamic properties. Their topological nature has important consequences on electron and heat transport, 15,16 which lead to novel features involving current-driven dynamics of skyrmion lattices.…”

The dynamics of individual magnetic skyrmions confined in ultrathin film dots is studied theoretically. The systems considered are transition metal ferromagnets possessing perpendicular magnetic anisotropy and particular attention is given to the dynamic response of the skyrmions to perpendicular driving fields. By using micromagnetics simulations, it is shown that breathing modes can hybridize with geometrically-quantized spin wave eigenmodes of the circular dots considered, leading to distinct features in the power spectrum that differ to the behavior expected for uniformly magnetized systems. The field dependence of the breathing modes offers a direct means of detecting and characterizing such skyrmion states in experiment.

“…Similar excitations were theoretically explored in two-dimensional magnetic systems, which evade ferromagnetic transitions by developing spatially inhomogeneous topological spin defects. 5,6,7,8 The topology is described by a quantized and conserved skyrmion number. The spin texture topology also "protects" skyrmions from scattering by structural defects, allowing them to be moved with ~10 5 times lower current density than a conventional magnetic domain 9 .…”

We show that properly engineered amorphous Fe-Gd alloy thin films with perpendicular magnetic anisotropy (PMA) exhibit bound pairs of like-polarity, opposite helicity skyrmions at room temperature. Magnetic mirror symmetry planes present in the stripe phase, instead of chiral exchange, determine the internal skyrmion structure and the net achirality of the skyrmion phase. Our study shows that stripe domain engineering in amorphous alloy thin films may enable the creation of skyrmion phases with technologically desirable properties.
