The spin density distributions of the of the stacked
(a) Ni(OH)2-BN, (b) Ni(OH)2-AlN and (c) Ni(OH)2-GaN heterostructures. The grey, red, pink, green, dark green, brown and blue balls represent Ni, O, H, B, Al, Ga and N atoms, respectively. The yellow and glaucous isosurfaces correspond to the spin up and spin down density, respectively (the isovalue is 0.05 a.u).
