Magnetic Properties of Fe₁₋ₓCoₓSi Single Crystals at Low Co Impurity Concentrations

Magnetostatic properties of FeSi and Fe0;98Co0;02Si single crystals have been studied. It has been found that the temperature and field dependences of the magnetization of monocrystal FeSi are strongly affected by introduction of a small amount of Co (2 %). A description of the results were provided by a model ac- counting for the formation of superparamagnetic iron clusters, as well as Fe-Co complexes. It is assumed that Fe-Co complexes form a ferromagnetic phase, which is approximately 0.6% of the Fe0;98Co0;02Si sample weigh

Spectrum of collective vibrations of vortex domain walls in a ferromagnetic nanostripe array

A problem of the spectrum of the collective periodic motion of vortex domain walls in a system of parallel ferromagnetic nanostripe is theoretically solved. The magnetic subsystems of stripes are coupled by the magnetostatic interaction. The effect of the distribution of vortex core polarities and chiralities on the character of periodic motion and the spectrum of collective modes of the nanostripe magnetization is discussed. Analytical expressions for the dispersion law and damping parameter of the collective periodic motion of vortex domain walls are obtained

On Nature of the Induced Anisotropy in the Chemically Deposited Со‒Р Films

Текст статьи не публикуется в открытом доступе в соответствии с политикой журнала.The induced magnetic anisotropy in the Со‒Р films prepared by chemical deposition from liquid solutions in a magnetic field has been investigated. The pronounced difference between the anisotropy values and relaxation times points out the existence of different physical mechanisms responsible for the occurrence of anisotropy of the Со‒Р films at low and high pH values. Possible mechanisms of the induced anisotropy in the Со‒Р films prepared at different pH values are discussed

Synthesis and Magnetic Properties of Crystals Bi2BaFe4O10

The paper presents the results of an experimental study of the first synthesized compound in the system Bi2O3-BaO-Fe2O3. It was found that the compound has cubic symmetry, the lattice parameters was determined. Electron microscopy measurements reveal that, in general, elemental composition of different parts of the samples corresponds to Bi2BaFe4O10 formula. According to magnetic measurements, the compound has a magnetic order with the magnetic ordering temperature TC = 700

Магнитные свойства монокристаллов Fe₁₋ₓCoₓSii при малой концентрации примеси Co

Magnetostatic properties of FeSi and Fe0;98Co0;02Si single crystals have been studied. It has been found that the temperature and field dependences of the magnetization of monocrystal FeSi are strongly affected by introduction of a small amount of Co (2 %). A description of the results were provided by a model ac- counting for the formation of superparamagnetic iron clusters, as well as Fe-Co complexes.

Обнаружено, что внесение небольшого количества примести Co (2 %) значительно влияет на температурные и полевые зависимости намагниченности монокристалла FeSi. Результаты обработаны в рамках модели, учетывающей образование суперпарамагнитных кластеров железа, а также комплексов Fe-Co. Предполагается, что комплексы Fe-Co образуют ферромагнитную фазу, которая составляет примерно 0,6 % от массы образца Fe0;98Co0;02Si
