This work was carried out in the framework of a collaboration
agreement between Max-Planck-Institut für
Festkörperforschung and Institute of Electronic Engineering
and Nanotechnologies ASM, and based upon experiments
performed at the NREX instrument operated by
Max-Planck Society at the Heinz Maier–Leibnitz Zentrum
(MLZ), Garching, Germany. The neutron part of the project
was supported by the European Commission under the
7th Framework Programme through the “Research Infrastructures”
action of the Capacities Programme, NMI3-II,
Grant Agreement number 283883, and by the project
STCU#5982.

By using waveguide enhanced polarized neutron reflectometry we have characterized the magnetic state of exchange biased CoO x(20 nm)/Co(4 nm)/Nb(5 nm)/Co(2 nm)/Nb(25 nm)/Al₂O₃ system. Measurement allowed to determine the dependence of the inclination angles of magnetic moment of the both Co layers as a function of applied field. According to the measurement the soft Co(2 nm) layer magnetization turns towards external field in magnetic fields as small as 20 Oe. In contrast direction of magnetic moment of Co(4 nm) layer cannot be altered in magnetic fields as high as 2 kOe.
