We have investigated the influence of spin accumulation on the domain wall resistance in the presence of the
Rashba and the Dresselhaus spin–orbit interactions. In this
order, we have employed a quantum kinetic model based
on the Wigner distribution function formalism. Using the
single-electron Hamiltonian and following the approach of
Šimánek and Rebei (Phys. Rev. B 71:172405, 2005), we derive the coupled differential equations for transverse spin accumulation components and then calculate its contribution
to the resistance of a domain wall. The results show that
both the Rashba and the Dresselhaus spin–orbit interactions
enhance the transverse spin accumulation and consequently
increase the domain wall resistance.
