WebJul 15, 2024 · This loss occurs because the atomic lattice at the interface behaves as a sink of spin angular momentum by the magnetic proximity effect or interfacial spin-orbit scattering. Then, the spin memory loss reduces the ISHE, SOT, and SHMR efficiency by decreasing the spin mixing conductance [ 9, 24 ]. Webcoupling (15–17), spin memory loss (SML) (18– 20) and two-magnon scattering (TMS) (21, 22) greatly reduce the interfacial transparency (23–25).
