Abstract :
In this paper, amorphous bilayer Gd/sub 40/Fe/sub 60/(100 nm)/Tb/sub 12/Fe/sub 88/(50 nm) the cooling field procedure. A uni-directional micro-magnetic model permits to reproduce the various measured hysteresis loop and give a full understanding of the magnetization reversal processes involved.
