This paper reports that further increase of magnetoresistance (MR) ratio to 6.5/spl sim/8.5% is achieved by using Fe/sub 50/Co/sub 50/ magnetic layers, in addition to current-confined-path(CCP)-nanooxide layer(NOL). The CCP-CPP structure is composed of Ta/Ru/PtMn/Co/sub 90/Fe/sub 10//Ru/pinned layer/NOL spacer/free layer/Cu/Ta cap. Using Fe/sub 50/Co/sub 50… CONTINUE READING
