TL;DR: Atomistic simulations indicate that the fluctuation state largely reduces the topological energy barrier and thereby enables the observed rapid and homogeneous nucleation of the skyrmion phase, and suggest a path towards ultrafast topological switching in a wide variety of materials through intermediate fluctuating states.

TL;DR: In this paper, the authors investigated laser-induced skyrmion generation in two different materials, mapping out the dependence of the process on the applied field and the laser fluence.

TL;DR: In this paper , a He+-ion beam is used to create well-defined skyrmion nucleation sites, which can be used to control individual skyrminions and motion with nanometer-scale precision.

TL;DR: The new laboratory setup allows systematic studies of optically induced spin and electron dynamics with element-specificity, particularly with MCD as the contrast mechanism with femtosecond temporal resolution and an unprecedented signal-to-noise ratio.

TL;DR: In this article , the influence of nanopatterned back-side aluminum masks on the optical excitation was studied in two sample geometries with varying layer sequence of substrate and magnetic Co/Pt multilayer.
