Rashba spin-orbit coupling enhanced magnetoresistance in junctions with one ferromagnet
Rashba spin-orbit coupling enhanced magnetoresistance in junctions with one ferromagnet
We explain how Rashba spin-orbit coupling (SOC) in a two-dimensional electron gas (2DEG), or in a conventional $s$-wave superconductor, can lead to a large magnetoresistance even with one ferromagnet. However, such enhanced magnetoresistance is not generic and can be nonmonotonic and change its sign with Rashba SOC. For an in-plane …
