Hybrid magnetoresistance in Pt-based multilayers: Effect originated from strong interfacial spin-orbit coupling

The hybrid magnetoresistance (MR) behaviors in Pt/Co(90)Fe(10)/Pt, Mn(1.5)Ga/Pt and Mn(1.5)Ga/Pt/Co(90)Fe(10)/Pt multilayers have been investigated. Both planer Hall effect (PHE) and angle-dependent MR in Pt/Co(90)Fe(10)/Pt revealed the combination of spin Hall MR (SMR) and normal anisotropic MR (AM...

description The hybrid magnetoresistance (MR) behaviors in Pt/Co(90)Fe(10)/Pt, Mn(1.5)Ga/Pt and Mn(1.5)Ga/Pt/Co(90)Fe(10)/Pt multilayers have been investigated. Both planer Hall effect (PHE) and angle-dependent MR in Pt/Co(90)Fe(10)/Pt revealed the combination of spin Hall MR (SMR) and normal anisotropic MR (AMR), indicating the large contribution of strong spin-orbit coupling (SOC) at the interfaces. When Pt contacted with perpendicular magnetic anisotropy (PMA) metal Mn(1.5)Ga, the strong interfacial SOC modified the effective anomalous Hall effect. The MR in Mn(1.5)Ga/Pt/Co(90)Fe(10)/Pt is not a simple combination of SMR and AMR, but ascribed to the complicated domain wall scattering and strong interfacial SOC when Pt is sandwiched by the in-plane magnetized Co(90)Fe(10) and the PMA Mn(1.5)Ga.
