Calculated Magnetic Properties of Zigzag Boron Nitride Nanoribbon

Substantial theoretical and experimental efforts have been made in the quest to find the candidates for future spintronics devices. Recently, the search for new spintronics materials has also included two-dimensional graphene-based materials due to the theoretical prediction that this type of material may show the half-metallic property. We present the results of an ab-initio density functional theory within a generalized gradient approximation study of zigzag Boron Nitride Nanoribbon (ZBNNR). Our results show different magnetic orderings. However, we found that, in general, narrow zigzag BN nanoribbon prefers a magnetic state depending on the shape and thus the orientation of the atoms on its edges. These results are especially noticeable for very narrow ZBNNR.
