Abstract
In the present case we measure specular and off-specular Polarized Neutron Scattering (PNR) from the specimen along each full magnetization loop: increasing (negative to positive) and decreasing (positive to negative) field sweeping direction of the H_a for the hysteresis loop with respect to the direction of H_FC. The specular intensity shows first order and weaker second order Bragg peaks at 25 and 50 mrad respectively corresponding to the bilayer thickness. In Neutron scattering magnetization rotation is identified by a significant increase of the specular reflectivities in the spin-flip (SF) channels, which correspond to in-plane magnetization components perpendicular to the guiding field.
