Аннотация: The comparison between the magnetic properties of materials with different curvature and spatial distribution of nanograins, such as particles (3D spatial distribution) and multilayer films (2D) was carried out. Functionally graded Co(P)/Ni(P) and Co(P)/CoNi(P) specimens have been fabricated by electroless deposition. The magnetic Показать полностьюand structural properties are characterized by electron microscopy, X-ray diffraction, ferromagnetic resonance spectroscopy, and vibrating sample magnetometer. It was demonstrated that the interaction between the Ni(P) core and Co(P) shell of particles could form the functionally graded materials with tailored structure and coercive force. Furthermore, it was found that the magnetic parameters (the local anisotropy field, ferromagnetic resonance linewidth, and coercivity) are mainly determined by the artificially created interface boundaries for all grains’ spatial distribution. The magnetic anisotropy field and coercivity of Co(P)/Ni(P) flat films were characterized by lower values than those for spherical shell of particles with the same composition, produced by the same method.
