Abstract

Effects of applied DC fields on the domain wall magnetization processes of Fe82Nb7B10Cu1 soft magnetic nanocrystalline ribbons at low frequencies were researched by impedance spectroscopy. Results show that small longitudinal DC fields help the domain wall unpin from the pinning field and large longitudinal DC fields increase the pinning field and damp the domain wall motion, while the transverse DC fields have little influence on the pinning field.
