Development and study of nanocrystalline and amorphous soft-ferromagnetic alloys
This thesis deals with the production, characterization and analysis of Fe and Co based nanocrystalline and amorphous soft-ferromagnetic alloys, alloys showing ferromagnetic hysteresis cycles with low energy losses, produced by the mechanical alloying (MA) and the melt spinning (MS) techniques.

| Sumario: | This thesis deals with the production, characterization and analysis of Fe and Co based nanocrystalline and amorphous soft-ferromagnetic alloys, alloys showing ferromagnetic hysteresis cycles with low energy losses, produced by the mechanical alloying (MA) and the melt spinning (MS) techniques. The study focus firstly on nanocrystalline alloys produced by MA from commercially available pure elements in powder form and later with alloys produced by milling of amorphous alloys previously produced in ribbon by the MS. The respective structural and magnetical properties are compared, including also an study of the anisotropy induced by the presence of an external magnetic field during the cooling process in the MS cases. |
