Abstract

Rapid stress annealing induced changes in structural and magnetic properties in Fe74.5Cu1Nb3Si 15.5B6 are reported. Obtained results suggest changes in spin texture with preferred orientation along ribbon axis. Fraction of A site in the DO3 lattice occupied by Si atoms, increases, with increase of applied stress during annealing. Volume fraction of the nanograins up to 60% (exhibiting quite similar mean grain diameter ∼9 nm) is observed. Lattice parameter values suggest that Si content in the nanocrystalline phase is between 14% and 19% and increase of lattice parameter suggests the elongation of the unit cell. Studied stress annealed samples exhibit soft magnetic behavior (coercive field ranging between 4 and 8 Am∈-∈1). Stress annealing reduces permeability whereas anisotropy field increases almost linearly exhibiting the induction of uniaxial and perpendicular to the ribbon axis anisotropy. Obtained stress-induced-anisotropy constant values range between 50 and 2,140 Jm∈-∈3.
