Observations reveal surface magnetic anisotropy and domain behavior in FeNbB ribbons, suggesting implications for material design.

To study the surface magnetic properties and domain structures in FeNbB ribbons after quenching and annealing.
Utilized magneto-optical Kerr effect for magnetization analysis.
Employed magneto-optical microscopy to observe domain behavior.
Investigated both as-quenched and strain-annealed FeNbB ribbons.
Identified a hard magnetic layer on the air side of the ribbon with a thickness of approximately 1.3 microns.
Found wide in-plane domains with 180-degree walls and overlapping narrow fingerprint domains.
Observed strip domains with magnetization primarily perpendicular to the ribbon axis from the surface layer.

Životský et al. (2010) studied this question.
