| Popis: | A new ferromagnetic metastable alloy of nominal composition Fe 62.5 Co 6 Ni 7.5 Zr 6 Cu 1 Nb 2 B 15 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. |
