The scattering field gradient maps of surface layer magnetic domains in
Y₂.₉₅La₀.₀₅Fe₅O₁₂ iron-yttrium garnet modified by high-dose ion implantation with
nitrogen ions N+
were obtained by the method of magnetic force microscopy. It was
found that improving the magnetic properties of thin films, which includes reducing the
observed magnetic losses after high-dose implantation, is accompanied by essential
ordering of magnetic domains on the surface of the implanted films. There is a direct
dependence of the magnetic properties on the dose of implanted atoms, accompanied by
a significant dispersion and amorphization of surface layer and formation of a clear
magnetic structure.
