Tanase, D. Pinzaru(Tanase), V. Georgescu] The effect of nitrogen addition on the morphology, magnetic anisotropy, and magnetoresistance properties of Co-Ni-N granular thin films were investigated. The films were grown by electrodeposition onto aluminum substrates at room temperature. By a complex process of cationic catalysis occurring at the cathode/electrolyte interface, nitrogen is adsorbed in the Co-Ni film. Finally, a granular film grows by a tridimensional progressive nucleation mechanism. The nature of the grains and of the interface between them influences exchange interactions between grains, which play an important role in determining the magnetic anisotropy. From the magnetic measurements, we found that the magnetic anisotropy constant varied in the range K eff=(−21.5÷36.6)×104J⋅m−3 and the coercivity varied between H c=(13÷67)kA⋅m−1 depending on the sodium nitrate content in the plating bath. The Co-Ni-N granular thin films display large values (∼160%) of magnetoresistance. These large values of magnetoresistance make such structures attractive for applications as sensitive magnetic field sensors.
