Understanding the magnetic proximity effect in a van der Waals heterostructure made of monolayers of semiconductor and ferromagnet is of great interest, considering its potential applications in spin control. This article presents a general method to study the problem, combining a\phantom\rule00exb i\phantom\rule00exn\phantom\rule00exi\phantom\rule00ext\phantom\rule00exi\phantom\rule00exo and tight-binding calculations. The results reveal that a spin-polarized miniband with a localized state forms in the heterostructure, and can be tuned magnetically, mechanically, or electrically. The authors furthermore propose some programmable spintronic nanodevices with various functionalities, for applications in scalable quantum computation and high-density quantum circuits.
