Abstract
The magnetization reversal of the free layer was studied in a pseudo spin-valve Gd-Co/Cu/Co structure prepared by thermal evaporation. The uniaxial magnetic anisotropy in a plane of the film was induced by applying the magnetic field during deposition. The angular dependence of the free Co layer coercivity was observed to be consistent with the Stoner-Wohlfarth rotation model. The switching field of this Co layer was found to be dependent on an additional constant magnetic field, oriented perpendicular to the anisotropy axis in a plane of the multilayered structure. This dependence confirms the possibility of additional regulations of the sensitivity of the spin-valve structure by the application of an appropriate bias field and could be useful for sensor applications.
