Topological spin structures: Growth and interaction with electrons and photons

The topological spin structures, such as skyrmions and merons, have increasingly been proposed as information carriers due to their topological characteristics and electrical maneuverability. Nevertheless, the difficulties in growing stable (especially stable under room temperature and zero magnetic fields) and large-scale topological lattices still restrict practical applications. This paper reviews the scientific efforts in facing this challenge comprehensively and simultaneously sums up the interaction between topological spin structures and current or light. The possibility of manipulating electron spin and photon chirality by the topological quasiparticles is emphatically discussed. This review paper aims to demonstrate scientific exploration for physical connotations on the interaction among topological quasiparticles and electrons and photons and to show the bridge built by researchers for the gap between scientific exploration and real-world application for topological spin structures.
