FIG. 1.

Dependence of magnetization as a function of an external magnetic field in antiferromagnetically coupled Co(10 nm)/Ru(0.5 nm)/Co(10 nm). The squares represent experimental data and the full line represents our fit with Aex = 1.55 × 10−11 J/m and J1 = 3 mJ/m2. The dashed line is our simulation assuming that Aex = ∞ and J1 = 3 mJ/m2.
