Abstract: Barkhausen noise properties of amorphous and nanocrystallized FINEMET type soft magnetic materials are investigated. It is obtained that the amorphous-nanocrystalline tranformation has a well observable effect on both the root main square, RMS, values and the critical exponents of the probability distributions of peak heights and durations.

Abstract: Finemet type materials show extremely soft magnetic behavior with excellent and in wide range on-demand variable macroscopic parameters [1]. Requirements for the most important magnetic parameters (e.g. permeability, coercitive force, saturation, loss) are determined by the targeted applications. We report results on the optimization of crystallization treatments and parameter tailoring by magnetic field induced anisotropy. As compared to the most widely used magnetic materials our samples have parameters of real measure of excellence.
