| description | A three-dimensional singular point that consists of two oppositely aligned emergent monopoles is identified in continuous CoTb thin films, as confirmed by complementary techniques of resonant elastic x-ray scattering, Lorentz transmission electron microscopy, and scanning transmission x-ray microscopy. This new type of topological defect can be regarded as a superposition of an emergent magnetic monopole and an antimonopole, around which the source and drain of the magnetic flux
overlap in space. We experimentally prove that the observed spin twist seen in Lorentz transmission electron microscopy reveals the cross-section of the superimposed three-dimensional structure, providing a straightforward strategy for the observation of magnetic singularities. Such a quasi particle provides an excellent platform for studying the rich physics of emergent electromagnetism. |
