Improvement of interfacial electron scattering by introduced NiFe nanoparticles

Ta/MgO/NiFe/MgO/Ta ultrathin films with and without intercalation of NiFe nanoparticles in MgO layers were prepared by magnetron sputtering, followed by a vacuum annealing process. The measured and calculated results show that the former has higher specular electron scattering (SES) parameter at MgO...

Zusammenfassung:Ta/MgO/NiFe/MgO/Ta ultrathin films with and without intercalation of NiFe nanoparticles in MgO layers were prepared by magnetron sputtering, followed by a vacuum annealing process. The measured and calculated results show that the former has higher specular electron scattering (SES) parameter at MgO/NiFe interfaces, lower resistivity, and higher magnetoresistance (MR). The improved transport properties (TPs) are mainly attributed to the suppressed diffuse electron scattering by means of the introduction of NiFe nanoparticles.
