“…The data obtained from the annealed samples showed X-ray diffraction peaks at the sets of angles characteristic of the body-centered cubic lattice structure of garnets, and revealed their crystalline microstructure. The average lattice constant and the crystallite size of the garnet films were calculated using identifiable diffraction lines and the standard methods explained in refs [29][30][31]. In this series of Bi 2.1 Dy 0.9 Fe 3.9 Ga 1.1 O 12 samples (prepared on quartz substrates using the above-mentioned process parameter variation types) the averaged XRD-derived lattice constant was close to 12.52 (±0.05) Å, and the theory-calculated [29] lattice constant corresponding to the garnet of nominal stoichiometry identical to that of the sputtering target was 12.53 Å.…”

To determine the approximate elemental composition of these thin films, energy dispersive spectroscopy (EDS) microanalysis experiments were carried out using an EDS Quantax Q100 (Bruker Corp., Billerica, MA, USA) system installed in conjunction with a scanning electron microscope (SEM).…”

Abstract:Highly bismuth-substituted iron garnet thin films are prepared on quartz substrates by using a radio frequency (RF) magnetron sputtering technique. We study the factors (process parameters associated with the RF magnetron sputter deposition technique) affecting the magneto-optical (MO) properties of ferrite garnet films of composition Bi 2.1 Dy 0.9 Fe 3.9 Ga 1.1 O 12 . All films show high MO response across the visible range of wavelengths after being annealed. In particular, the effects of substrate stage temperature and rotation rate on the various properties of films are studied. Experimental results reveal that the characteristics of garnet films of this type can be tuned and optimized for use in various magnetic field-driven nanophotonics and integrated optics devices, and that, at a substrate stage rotation rate near 16 revolutions per minute, the MO quality of the developed MO films is the best, in comparison with films deposited at other rotation rates. To the best of our knowledge, this is the first report on the effects of deposition parameters on the properties of garnet films of this stoichiometry.

Abstract:Behavior of spin wave propagation in ferromagnetic medium with non-uniform distribution of magnetic parameters is studied. In particular, the influence of external magnetic field, spin-wave frequency and exchange parameter on the behavior of surface spin wave propagate through inhomogeneity made in the form of lens (lens is biaxial ferromagnet placed into uniaxial ferromagnetic medium. Ferromagnets are in the homogeneous magnetic field directed along the hard axis of biaxial ferromagnet) is studied.

“…The parameters of certain types of domain structures (DS) and their separate elements have been widely studied both by experimental and theoretical methods, for example [1][2][3][4][5][6]. These papers report on thermodynamic properties of ferromagnetic materials, the influence of DS on their magnetization processes and their practical use in magnetic devices.…”

Ordinary cylindrical specimens with easy-axis anisotropy perpendicular to the axis of a cylinder are studied. As shown, the inhomogeneous long-wave magnetic configurations of harmonic type can be created and observed in such samples. A linear theory is developed to simplify the set of LandauLifshitz and Maxwell's equations to one general equation for a magnetostatic potential. The ranges of magnetic fields and the self-parameters responsible for the inhomogeneous periodic configuration formation are determined when solving a boundary value problem for a magnetostatic potential. Dependence of the period of magnetization wave on a magnetic field value, the constant of anisotropy and diameter of a cylinder is determined. The proposed theory gives qualitative explanation of the experiment when, using the Bitter's powder-like figures' method, quasi-periodic distributions of the magnetostatic fields can be observed in samples. These fields arise under external magnetic field of about 1 kOe directed along the axis of a steel cylinder and are absent without external magnetic field. An example of practical application of long-wave magnetic structures for a surface morphology control during chemical etching of ferromagnetic metals in acid solutions is given. The quasi-periodic structure of a corrosion surface of ferromagnetic cylinder corresponds to the period of a long-range magnetic structure.Key words: ferromagnets, domain structure, magnetostatic field, etching.Досліджено циліндричні зразки з легковісною анізотропією, перпенди-кулярною до осі циліндру. Показано, що в таких зразках можна створю-вати і спостерігати неоднорідні довгохвильові магнетні конфіґурації гар-монічного типу. Було розвинуто лінійну теорію, яка зводить систему рів-нянь Ландау-Ліфшиця та Максвеллових, що описують магнетний стан системи, до одного загального рівняння для магнетостатичного потенція-лу. В ході розв'язання крайової задачі для магнетостатичного потенціялу визначено діяпазон магнетних полів і власних параметрів системи, за яких ймовірним є утворення неоднорідної періодичної конфіґурації. Ви-значено залежність періоду хвилі намагнетованости від амплітуди магне-тного поля, константи анізотропії та діяметра циліндру. Запропонована теорія дає якісне пояснення експерименту, коли при застосуванні Бітте-рової методи порошкових фіґур можливе спостереження квазиперіодич-них розподілів магнетостатичних полів, що утворені при прикладанні зовнішнього магнетного поля порядку 1 кЕ вздовж осі сталевого цилінд-ру, тоді як без прикладання зовнішнього магнетного поля магнетостатич-ні поля відсутні. Наведено приклад практичного застосування довгохви-льових магнетних структур для керування морфологією поверхні при хе-мічному щавленні феромагнетних металів у розчинах кислот. При цьому квазиперіодична структура поверхні кородованого феромагнетного цилі-ндра відповідає періоду його довгомасштабної магнетної структури.Ключові слова: феромагнетики, доменна структура, магнетостатичне по-ле, щавлення.Исследованы цилиндрические образцы с легкоосной анизотропией, пер...
