Investigation of magnetic properties and micromagnetic structure of multicomponent Fe61.4Ni3.6Cr3.2Si2.4Nb7.8Mn3.6B18 amorphous ribbons

Magnetic-field behavior of heterogeneous magnetic materials

“…At last, one can note that we had also observed the abnormal MOKE hysteresis loops (up to partially and completely inverted hysteresis loops) for the annealed at T ¼ 380-550 1C Fe 80.5 Nb 7 B 12.5 ribbons [10][11][12]. The bulk hysteresis loops of these ribbons (in contrast to the thin-film Co/Ni/Fe and Fe/Zr/Fe samples) had the usual forms.…”

“…have heterogeneous near-surface microstructure. The consideration of a two-phase model with two nonidentical (amorphous and nanocrystalline) phases and interface antiferromagnetic exchange between those allowed to explain the MOKE hysteresis loops, revealed for the above ribbon samples [10].…”
