Abstract :
The magnetic properties of ultrathin Fe75Al4Nb5B12Cu1 nanocrystalline alloy ribbons with 9 μm thickness and the effect of Al additions to Fe-B-Nb-Cu alloy for improving the high-frequency magnetic properties were investigated. It was found that the effective permeability at frequencies over 100 kHz was higher and the core loss was lower for the composition Fe75Al4Nb5B12Cu1 alloy. Moreover, the reduction of the ribbon thickness to 9 μm was very effective in improving their permeability and the core loss characteristics up to the MHz frequency range
