On the other hand, in the above heterostructure, not only the magnetic side was modulated by NbSe2 (Zeeman-type SOI), but also the electronic state of the NbSe2 side was modulated by the magnetism. In particular, when the magnetization is induced in NbSe2 through the interface proximity effect, the band modulation by magnetization and Zeeman-type SOI was coupled and a state called ferro-valley ferromagnetism was realized2. In this presentation, we will discuss the transport properties of the ferro-valley ferromagnetic state revealed through the details of the transport properties of this heterostructure.
