Magnetic and magnetoelastic behavior of Co-substituted Fe-Cu-Nb-Si-B amorphous alloys

Amorphous and nanocrystalline Fe-based alloys are becoming increasingly interesting for more efficient energy distribution systems and/or for miniaturized sensors and related devices. In this work structural, magnetic and magnetoelastic properties of Co-substituted FINEMETTM-type and VITROPERM 800
