Rashba spin-orbit coupling enhanced magnetoresistance in junctions with one ferromagnet
Source abstract
Abstract
The spin and orbital motion are coupled because the electron spin interacts with a relativistic magnetic field, generated by moving charges that the electron sees in its rest frame. While the celebrated Rashba spin-orbit coupling (SOC) has been studied for decades, the authors reveal here, using novel symmetry, that even simple trends regarding its strength are not understood. Unlike the common understanding that stronger Rashba SOC should enhance many phenomena, from magnetoresistance to exotic spin-triplet superconductivity, the authors propose and experimentally confirm a more nuanced picture in which strong Rashba SOC in junctions with single ferromagnets can be either a friend or a foe.
