Abstract :
Summary form only given. We have prepared hard-soft spin valve structures by ultra-high vacuum evaporation. We have used an asymmetric CoFe/Ir/CoFe artificial ferrimagnet as a hard magnetic layer and an Fe/Co bilayer as a soft detection layer. In order to have more details on the reversal mechanism of the soft layer we have zoomed the magnetization curve around zero field.
