Description
Moiré superlattices in two-dimensional magnetic/superconducting heterostructures offer a powerful platform for engineering and tuning the interplay between magnetism and superconductivity. Here, we fabricate a NiI₂/NbSe₂ heterostructure via molecular beam epitaxy, where NiI₂ serves as a two-dimensional van der Waals magnet with intrinsic spiral magnetic order. Using low-temperature scanning tunneling microscopy/spectroscopy, we observe that the superconductivity within the magnetic film is modulated by the moiré pattern, accompanied by moiré-tuned edge states and Yu–Shiba–Rusinov (YSR) states at the boundary. Our findings establish moiré engineering as an effective route to control magnetic and superconducting interactions, providing a promising platform to investigate unconventional in-gap states and edge excitations in two dimensions.
