Figure 7.

Room-temperature magnetic hysteresis loops of two samples consisting of four trilayers and corresponding illustrations. Each trilayer consists of an 8-nm-thick obliquely deposited (54°) Co layer; a normally deposited Co layer of variable thickness (6 nm for the sample displayed in (a) and 12 nm for the sample displayed in (b)); and an obliquely deposited (54°) 6-nm-thick Ta spacer layer. Each sample was also deposited on an obliquely deposited 6-nm-thick Ta buffer layer.
