Hysteresis loops at $Q=0.49$ and $0.38{\mathrm{nm}}^{-1}$ for Co (■) and Fe (red ●), respectively. Inset: representations of the x-ray experiment and sample.Reuse & Permissions

Figure 2

Spin density depth profiles for Co (blue) and Fe (red) spins obtained from the specular x-ray reflectivities (inset) at $H_{\pm }=\pm 796\mathrm{kA}/\mathrm{m}$.Reuse & Permissions

Figure 3

Polarized neutron reflectivity (symbols) measured with field along $[\overline{1}10]$ ${\mathrm{FeF}}_2$. The solid curves were calculated from a model whose magnetization depth profile is shown in Fig. 4. Inset: representation of the neutron experiment.Reuse & Permissions

Figure 4

Depth dependence of the vector magnetization (inset, 3D view), magnitude (blue curve, $|M|$), and angular deviation $\varphi$ (red curve) from the applied field in the sample plane deduced from neutron scattering. Error bars represent deviations of depth profiles with indistinguishable ${\chi }^2$. The magnetization used in the OOMMF simulation (cyan ●) and the values of $\varphi$ (green ■) obtained from the simulation. The sum of the Fe and Co spin density profiles for $H\parallel$ [001] ${\mathrm{FeF}}_2$ (obtained from Fig. 2 in arbitrary units using x-ray scattering) is shown in absolute units (○).Reuse & Permissions
