Crystalline, Magnetic and Domain Structure of Epitaxial Ferrite-Garnet Films (Review)

<span>The article gives a literary review of the current state of research of ferrite-garnet films. The basic crystalline and magnetic characteristics of thin films of iron-yttrium garnet are considered. We analyzed the causes of the appearance of the labyrinth, stripe and cylindrical domain structure. It is shown that the domain structure of the yttrium iron garnet strongly depends on many parameters of the films, in particular on the thickness, structural perfection of the surface and the sample as a whole. The article reviews the most common methods of synthesis, ion implantation and post-growth treatment of ferrite-garnet films. The study of dependencies between the conditions of obtaining, the chemical composition, the post-treatment conditions, the defective structure and the magnetic properties of ferrite-garnet films have great practical value for obtaining films with predetermined properties. </span><br /><strong>Key words:</strong><span> Domain structure, Yttrium-iron garnet, LaGa-substitution, magnetic properties, lattice parameter.</span>
