Abstract
A new ferromagnetic metastable alloy of nominal composition Fe62.5Co6Ni7.5Zr6Cu1Nb2B15 characterised by high amplitude of magneto-elastic wave has been recently introduced. Suitable thermal treatments have been found to induce in this system a nanocrystalline phase. In this work the magneto-impedance behaviour has been studied as a function of microstructure in samples submitted to different annealing conditions such as conventional and current annealing. A strong correlation among microstructure, average magnetic anisotropy and magneto-transport properties has been found. A comparison with magneto-acoustic wave measurements has been performed.
