Manipulation and Optical Detection of Artificial Topological Phenomena in 2D Van der Waals Fe₅ GeTe₂ /MnPS₃ Heterostructures.

ABSTRACT: 2D ferromagnet is a good platform to investigate topological effects and spintronic devices owing to its rich spin structures and excellent external-field tunability. The appearance of the topological Hall Effect (THE) is often regarded as an important sign of the generation of chiral spin textures, like magnetic vortexes or skyrmions. Here, interface engineering and an in-plane current are used to modulate the magnetic properties of the nearly room-temperature 2D ferromagnet Fe₅ GeTe₂ . An artificial topology phenomenon is observed in the Fe₅ GeTe₂ /MnPS₃ heterostructure by using both anomalous Hall Effect and reflective magnetic circular dichroism (RMCD) measurements. Through tuning the applied current and the RMCD laser wavelength,
