摘要：
The field and frequency dependences of the magnetic permeability in soft magnetic electroplated FeNiMo/Cu microwires were studied by means of their magneto impedance response. We analysed the influence of electroplating parameters such as current density, electrolyte composition and the presence of a magnetic field. It was found that the introduction of Mo as a third non-magnetic component causes large changes in the film permeability, which are associated with compositional and morphological effects. The electrodeposition under an external magnetic field induces a unidirectional anisotropy with the appearance of a large Barkhausen effect.
