Exotic material properties and appealing phenomena have emerged as a new frontier trend to investigate the low-dimensional systems with a strong spin-orbit coupling. Within the scope of present studies, the spinpolarized
scanning tunneling microscopy (SP-STM) technique provides an ideal tool to explore the crucial role in delicate electronic and magnetic spin structures of various systems ranging from the scale of bulk down to atomic level. Besides, a new class of non-collinear spin textures, i.e., chiral domain wall, spin spiral and magnetic skyrmion etc., has also been recently observed in magnetic films and multilayers on heavy metal substrates due to the lack of spatial inversion symmetry and sizable interfacial Dzyaloshinskii-Moriya (DM) interaction. In particular, the
isolated magnetic skyrmions have received an intensive amount of interest in terms of their thrilling perspectives for the future application of
magnetic information technology.
