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
