Magnetic order in NbS2 nanoribbons

Transition metal dichalcogenides are well known for their laminar structure, similar to that of graphite. The bulk structure of many of them has been the subject of several studies during the last 30 years, due to their many potential technological applications. In the year 2004, Novoselov et al. ac...
