摘要

Abstract

Topological spin structures of light

including the Skyrmion

Meron

and bi-Meron

are intriguing optical phenomena that arise from spin–orbit coupling. They have promising potential applications in nano-metrology

data storage

super-resolved imaging and chiral detection. Aside from the electric part of optical spin

of equal importance is the magnetic part

particularly the H-type electromagnetic modes for which the spin topological properties of the field are dominated by the magnetic field. However

their observation and measurement remains absent and faces difficult challenges. Here

we design a unique type of anapole probe to measure specifically the photonic spin structures dominated by magnetic fields. The probe is composed of an Ag-core and Si-shell nanosphere

which manifests as a pure magnetic dipole with no electric response. The effectiveness of the method was validated by characterizing the magnetic field distributions of various focused vector beams. It was subsequently employed to measure the magnetic topological spin structures

including individual Skyrmions and Meron/Skyrmion lattices for the first time. The proposed method may be a powerful tool to characterize the magnetic properties of optical spin and valuable in advancing spin photonics.
