Anisotropic magnetoresistance in 2DEG with Rashba spin-orbit coupling
Journal of Magnetism and Magnetic Materials, 2018•Elsevier
We calculate the anisotropic magnetoresistance (AMR) in two dimensional electron gas
(2DEG) with Rashba spin-orbit coupling, when the Fermi energy lies at the crossing point of
the two energy bands, in the presence of dilute magnetic charged impurities. We use the
semiclassical Boltzmann equation and solve it exactly by an ansatz with an anisotropic
parameter that is interpreted as a transport time vector. AMR is zero if the electric
contribution to scattering overcomes the magnetic one, otherwise it is finite.

We calculate the anisotropic magnetoresistance (AMR) in two dimensional electron gas (2DEG) with Rashba spin-orbit coupling, when the Fermi energy lies at the crossing point of the two energy bands, in the presence of dilute magnetic charged impurities. We use the semiclassical Boltzmann equation and solve it exactly by an ansatz with an anisotropic parameter that is interpreted as a transport time vector. AMR is zero if the electric contribution to scattering overcomes the magnetic one, otherwise it is finite.
