Perpendicular surface magnetic anisotropy in an amorphous ferromagnet induced by adsorption occurring through the mechanism of the formation of hydrogen bonds

Domain Structure Reversible Reconstruction and Changing of Domains Width in Ferrite-Garnet Films Caused by Water Molecules Adsorption

“…Sum of initial magnetic anisotropy constant and surface magnetic anisotropy induced by water molecules adsorption leads to the reduction of effective perpendicular magnetic anisotropy constant of the film. We observed the effect of appearance of the surface perpendicular magnetic anisotropy in an amorphous ferromagnet due to adsorption of water and methyl alcohol molecules [7]. Energy of initial perpendicular magnetic anisotropy attributed to the film unit area (К⋅h) is ∼0.8 erg/сm 2 .…”

Uniaxial Magnetic Anisotropy of Bismuth-Doped Ferrite-Garnet Films, Induced by Weak Adsorption

“…Earlier we revealed the effect of weak adsorption of water and methanol molecules, reversible at room temperature, on the magnetic properties of ferromagnetic metals: on Fe whiskers and amorphous Fe-based ferromagnetic strips. It has been shown in particular that reversible adsorption-desorption processes proceeding through the formation of hydrogen bonds induce perpendicular surface magnetic anisotropy in the amorphous ferromagnet [1]. The perpendicular anisotropy results in the appearance of the normal magnetization component on the surface and the rearrangement of the magnetic domain structure.…”
