the final..

FePtCu(5nm)/MgO sub

FePtCu(5nm)/MgO(3.2)/MgO sub w/o MgO annealing

    MgO with Power 50W 200W at 2mTorr

    MgO with Power 50W 200W at 15mTorr

FePtCu(5nm)/MgO(3.2)/MgO sub annealing the MgO at 600oC for 30 min

    MgO with Power 50W 200W at 2mTorr

    MgO with Power 50W 200W at 15mTorr

-> prependicular anistropy in FePtCu/MgO system is dominated by the surface state of MgO (only analysis via magnetic propties could be studied..)

[FePtCu/MgO]6/SiO2 – defective MgO
[FePtCu/MgO]6/SiO2 – cleaner MgO

MgO with Power 50W 200W at 2mTorr

MgO with Power 50W 200W at 15mTorr

-> for more microstructural, mangtical analysis..

1. Rate of MgO at 50W at 2 & 15mTorr
2. Rate of FePtCu at 2mTorr
