  The kagome lattice Co$_3$Sn$_2$S$_2$ exhibits the quintessential topological
phenomena of a magnetic Weyl semimetal such as the chiral anomaly and Fermi-arc
surface states. Probing its magnetic properties is crucial for understanding
this correlated topological state. Here, using spin-polarized scanning
tunneling microscopy/spectroscopy (STM/S), we report the discovery of localized
spin-orbit polarons (SOPs) with three-fold rotation symmetry nucleated around
single-S vacancies in Co$_3$Sn$_2$S$_2$. The SOPs carry a spin-polarized
magnetic moment and a large orbital magnetization of a topological origin
associated with the Berry phase and the persistent circulating current.
Appreciable magneto-elastic coupling of the SOP is detected by atomic force
microscope and STM. Our findings suggest that the SOPs can enhance magnetism
and stability of the magnetic Weyl nodes for more robust
time-reversal-symmetry-breaking topological phenomena. Controlled engineering
of the SOPs may pave the way toward practical applications in functional
quantum devices.
