Domain Structure Reversible Reconstruction of Amorphous Ferromagnetic by Water Molecules Weak Adsorption

Abstract:

Influence of water molecules reversible adsorption on domain structure and domain wall structure in amorphous Fe-rich ferromagnet samples is investigated by magnetooptical method. Before investigation the samples were kept in the air. Domain structure of the samples significantly changes in wacuum: instead one 180-degree domain wall several domain walls appear which are oriented with angle 45o to the long side of the sample. This effect is completely reversible. Another new effect is found: domain wall width on the sample surface in vacuum is 35% bigger (13.5 µm) than in atmosphere of water vapor (10 µm).
