We predict an accepted configuration of hexagonal boron nitride (BN) layer on Co(111) surface by first-principles calculations. The calculated adsorption energy of this configuration is around −0.51 eV with a corrugation close to 0.1 Å. Polarized spin states are induced in BN layer due to the hybridization of the BN layer with the substrate Co, which gives rise to a magnetic moment of 0.2 μB on each pair of BN. The finding of high spin polarization on the absorbed BN layer ensures a high degree of passage of the preferred spin and is important in the development of nanoscale devices for spintronics applications.
► The growth of a precisely single layer BN on the Co(111) surface is possible.
► A magnetic moment of 0.2 μB was induced on each pair of BN.
► The high spin polarization in BN layer ensures a perfect passage of spin electrons.
