Magnetism and perfect spin filtering in pristine MgCl nanoribbons modulated by edge modification.

The search for new materials, with ideal electronic and magnetic properties for potential applications in nanoelectronics, has been extremely successful so far, and has paved the way for us to reimagine all technological devices. In the present work, we study the design of MgCl nanoribbons for applications in nanoelectronics and spintronics, by employing first-principles calculations based on density functional theory (DFT) and non-equilibrium Greens function techniques. Our results show that the properties of MgCl nanoribbons depend strongly not only on their geometrical form (armchair or zigzag) but also on the atoms at their edges.
