Properties of the "thin" structure domain walls in rare-earth ortho-ferrites

Dynamics of thin-structure domain walls (DW) has been studied taking into account of the g-factor anisotropy. The line speed has been found as a function of the DW motion speed different from that known before. A 180-deg DW of the Neel type with a zero-deg Bloch line localized thereon has been consi...

Description
Summary:Dynamics of thin-structure domain walls (DW) has been studied taking into account of the g-factor anisotropy. The line speed has been found as a function of the DW motion speed different from that known before. A 180-deg DW of the Neel type with a zero-deg Bloch line localized thereon has been considered using numerical methods. The law of the magnetization vector turning, effective widths of the DW and line, and energy per unit line length have been determined for such a DW. The more precise taking of the DW bidimensionality into account has been shown to result in significant differences as compared to the approximate analytical methods.
