  It is known that there is a wide class of quasi-two-dimensional graphenelike
nanomaterials which in many respects can outperform graphene. So, here in
addition to graphene, the attention is directed to stanene (buckled honeycomb
structure) and phosphorene (puckered honeycomb structure). It is shown that,
depending on the doping, these materials can have magnetically ordered edges.
Computed diagrams of magnetic phases illustrate that, on the one hand, n-type
doped narrow zigzag nanoribbons of graphene and stanene have
antiferromagnetically aligned magnetic moments between the edges. On the other
hand, however, in the case of phosphorene nanoribbons the zigzag edges can have
ferromagnetically aligned magnetic moments for the p-type doping. The edge
magnetism critically influences transport properties of the nanoribbons, and if
adequately controlled can make them attractive for spintronics.
