Barkhausen Noise Measurements in Amorphous and Nanocrystalline FINEMET Type Alloys

Abstract:

Article Preview

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.
