Tunable Spin‐Polarized States in Graphene on a Ferrimagnetic Oxide Insulator (Adv. Mater. 8/2024)

2D Spintronics In article number 2305763, Junxiong Hu, Zhenhua Qiao, A. Ariando, and co-workers demonstrate the emergence of robust spin-polarization in graphene on a ferrimagnetic insulating oxide Tm3Fe5O12 (TmIG) with large spin-splitting energy of up to hundreds of meV. Moreover, the induced spin-splitting energy can be tuned over a broad range by field cooling technique. The observed spin polarization in graphene with large and tunable spin-splitting energy promises the field of 2D spintronics for low-power electronics.
