It was found that the Co/Ni multilayer and the CoFeB layer have Ru thickness dependent oscillatory interlayer coupling. Due to its interlayer coupling with the perpendicularly magnetized Co/Ni multilayer, the CoFeB magnetization direction is slightly tilted out-of-plane from its in-plane magnetic easy axis. Quantitative measurements show that the tilting angle is small (< 12 degrees) and that a small in-plane magnetic field (similar to 50 Oe) applied to this structure will result in a completely in-plane CoFeB magnetization.
