  • Abstract
    This paper reports the enlargement of pinning field, Hp, in spin-valves with α-Fe2O3 as a pinning layer utilizing a Co/Ru/Co synthetic antiferromagnet as the pinned layer. Hp of α-Fe2O3/Co is only 18 kA/m with a 20-nm-thick α-Fe2O3 layer. On the other hand, Hp is improved over 40 kA/m by replacing the pinned layer with Co/Ru/Co synthetic antiferromagnet. We studied the dependence of Hp in α-Fe2O3 spin-valves with the Co/Ru/Co on Ru and α-Fe2O 3 layer thickness
