Control of the nonlinear frequency shift for the spin-transfer nanooscillator using a bias magnetic field

We investigated the possibilities of controlling the nonlinear frequency shift of the magnetization oscillations in a spin-transfer nanoscillator by varying the magnitude and direction of the bias magnetic field. We considered both isotropic ferromagnetic materials and crystals with uniaxial and cubic crystallographic anisotropies. We have shown that achieving a zero nonlinear frequency shift is possible with a certain orientation of the bias magnetic field vector. The results of the theoretical analysis based on the method of Hamiltonian formalism are in good agreement with the micromagnetic simulations. Our research reveals the way to control the frequency tuning of a spin transfer nanoscillator, which is crucial for spintronic signal generation devices.Comment: 6 pages, 3 figure

Ethnodemography of Bashkirs in Regions of Russia (1970—2010)

The issues of ethno-demographic and ethno-linguistic development of the Bashkir population in the regions of the Russian Federation are considered. It is noted that the tendencies of demographic processes among the Bashkirs in the regions and in the republic of the same name are very different. The features of the ethnodemographic development of the Bashkirs in the regions of their historical settlement are shown, in which general trends coincide with the demographic processes in the country as a whole. It cannot be said about the Republic of Bashkortostan, which is characterized by sharp fluctuations in the size of the titular ethnic group. The dynamics of the ethnic and linguistic identity of the Bashkir population in the regions of historical settlement is revealed in a comparative aspect with the subjects to which the Bashkirs moved at a later time and in which their number is a small proportion. The novelty of the study lies in the fact that it was the first to analyze the ethno-demographic and ethno-linguistic aspects of the development of the Bashkirs in the Russian Federation, including in the regions of their historical settlement. The relevance of the study is due to the fact that the issue of the demographic development of the Bashkir population at the present stage, especially in the republic of the same name, has acquired an ethnopolitical discourse. It has been proven that, despite the policy of reviving ethnicity and the native language, the Bashkirs, like other peoples, are gradually losing it in favor of being recognized as a native Russian

Reaction of diethyl 3-methyl-1,2-butadienylphosphonate with 1,10-diaza-18-crown-6

Reaction of two-fold excess of diethyl 3-methyl-1,2-butadienylphosphonate with 1,10-diaza-18- crown-6 leads to the formation of an adduct whose molecule includes two 1-phosphoryl-3-methyl-2-butene fragments bound together by a crown bridge with the anti location of organophosphorus groups relative to the macrocycle plane. The 1,2-multiple bond of the phosphonate is involved in the reaction. Extraction properties of the diphosphorylated crown ether toward alkali metal picrates were studied. © Pleiades Publishing, Ltd., 2009

Annealing of PrF3 nanoparticles by microwave irradiation

The influence of microwave irradiation on the recovery of nanocrystalline PrF3 powders has been experimentally analyzed by nuclear magnetic resonance (NMR) at T = 1.5 K. It is established that the relaxation times of 141Pr and 19F nuclei rise significantly with an increase in the hydrothermal-treatment time, whereas the 141Pr NMR spectra narrow, which indicates a decrease in the number of defects in the lattices of nanosamples. © 2014 Pleiades Publishing, Ltd
