The magnetoresistance of a one-dimensional electron gas in a metallic ferromagnetic nanowire containing two atomic-size domain walls has been investigated in the presence of spin-orbit interaction. The magnetoresistance is calculated in the ballistic regime, within the Landauer-Büttiker formalism. It has been demonstrated that the conductance of a magnetic nanowire with double domain walls...

Strong spin-orbit coupling in noncentrosymmetric materials and interfaces results remarkable physical phenomena, such as nontrivial spin textures, which may exhibit Rashba, Dresselhaus, other intricated configurations. This provides a promising basis for nonvolatile spintronic devices further implications. Here, we simulate from first principles two-dimensional electron gas ultrathin platinum p...

We study the bound state spectrum and the conditions for entering a supercritical regime in graphene with strong intrinsic and Rashba spin-orbit interactions within the topological insulator phase. Explicit results are provided for a disk-shaped potential well and for the Coulomb center problem.
