Layer-resolved magnetic proximity effect in van der Waals heterostructures
Magnetic proximity effects are integral to manipulating spintronic 1 , 2 , superconducting 3 , 4 , excitonic 5 and topological phenomena 6 – 8 in heterostructures. These effects are highly sensitive to the interfacial electronic properties, such as electron wavefunction overlap and band alignment. T...
