Extended Data Fig. 1: Evidence that magnetization comes from the N-C boundary of zGNR and hBN.
From: Signatures of magnetism in zigzag graphene nanoribbons embedded in a hexagonal boron nitride lattice
Topography (a) and friction (b) images of an epitaxial zGNR acquired by AFM. The zoom-in lateral force image of zGNR area is marked by circle in (b), which indicates the zigzag orientation of graphene ribbon65. (c) The ODMR result of the same ribbon in iso-B mode, showing magnetic signal along the graphene ribbon-BN boundary by NV scanning. (d) A typical nc-AFM image of the epitaxial grown ribbon from a step edge of hBN in constant-height mode, corresponding to the area marked as green square in (b). (e) Force spectroscopies taken on different atoms at the ribbon-BN boundary. Insert: A zoom-in view of the boundary of graphene-BN at atomic resolution in the area marked as a yellow square in (d), here boron atoms in red, carbon atoms in black and nitride atoms in blue.
