Enhanced planar hall sensitivity with better thermal stability by introducing interfacial modification of Au spacer
چکیده انگلیسی
This paper reports an enhancement of planar Hall sensitivity in NiFe/Au/IrMn multilayers by introducing interfacial modification. The improvement of the sensitivity derives from the increase of resistivity change (Δρ), which is attributed to strengthened spin-asymmetry of polarized electrons in NiFe layer induced by strong spin-orbit scattering of Au layer. Furthermore, the NiFe/Au/IrMn structure based sensor exhibits good thermal stability. The high sensitivity together with good thermal stability makes the NiFe/Au/IrMn structure based sensor very promising for bio-detections.
