Abstract

Obliquely sputtered Ta underlayers were used to stabilize antiferromagnetically couple Co/Ru/Co/Ta structures with a strong uniaxial anistropy. Magneto-optical indicator film (MOIF) imaging revealed nucleation and growth of domains during remagnetization. For 0.5 nm Ru thickness and 10.6 nm Ta thickness, the top film magnetization is canted 82 from bottom film. The canting is attributed to ferromagnetic coupling through pinholes.
