Abstract
The soft magnetic properties of mechanically alloyed nanostructured FINEMET powder cores were studied using magnetic measurements and impedance spectr oscopy. The initial permeability of the nanostructured powder core was foun d to be constant up to 5 MHz frequency range. The minor addition of Al for Si significantly improves the softness of the FINEMET alloys. The optimum i nitial permeability and minimum core losses were obtained for 1 at.% of Al addition. This study shows the possibility of using nanostructured powder c ores for high frequency applications. (C) 2001 Elsevier Science B.V. All ri ghts reserved.
