| Research Abstract |
The full epitaxial stacked films with AML [Fe/Co]n/Cu or Ag/ AML [Fe/Co]n for CPP-GMR measurement were confirmed on the electrode of Au on MgO(001) substrate by the RHEED and TEM observation. We have estimated the spin asymmetry coefficient (β and γ) of the AML[Fe/Co] /Cu or Ag/AML [Fe/Co]n from the fitting of the plot of ΔRA as a function of thickness of ferromagnetic layer (tFM) by the Valet-Fert theory.The bulk asymmetry in our epitaxial SV with AML[Fe/Co] were found to be β=0.76 - 0.81. Also we achieved the interface asymmetry coefficient (γFM/NM) value of 0.81±0.03, 0.84±0.02 using Cu and Ag spacer with AML[Fe/Co]n, respectively.
