FIG. 1.

Low-angle XRD data from the bilayer. The short wavelength oscillations at low angles arise from the total thickness of the film while the longer wavelength oscillations at higher angles are due to the finite thickness of the Fe layer. The fit to the experimental data gives the following result: , and a interface roughness of .

FIG. 2.

VSM measurements in the direction parallel to the applied magnetic field. The field is applied 0° (a), 45° (b), and 90° (c) with respect to the bias direction. The hysteresis loop is shifted when the unidirectional anisotropy has a component along the field direction [(a) and (b)], while there is an intermediate magnetic state for the perpendicular field orientation [(c)].

FIG. 3.

VSM measurements in the direction perpendicular to the applied magnetic field. The field is applied 45° (a) and 90° (b) with respect to the bias direction. In both cases, the magnetic moment along the bias direction increases when the field is reduced from saturation.

FIG. 4.

The relationship between the bias direction (BIAS), the direction of the neutron guide field (GF), and the saturation direction . Saturation along the Fe[110] direction (a); the guide field was first applied parallel to Fe[100] and then Fe[010]. Saturation along the Fe[-1-10] direction (b); the guide field was first applied parallel to Fe[-100] and then Fe[0-10].

FIG. 5.

Spin-dependent neutron reflectivity for incident neutron spin parallel and antiparallel to the applied field. The solid and dashed lines are fits to the data. A splitting of and indicates that there is a net magnetic moment parallel (or antiparallel) to the applied magnetic field. and (a); and (b); and (c); and and (d).
