Peculiarities of the stochastic motion in antiferromagnetic nanoparticles

Antiferromagnetic (AFM) materials are widely used in spintronic devices as passive elements (for stabilization of ferromangetic layers) and as active elements (for information coding). In both cases switching between the different AFM states depends in a great extent from the environmental noise. In the present paper we derive the stochastic Langevin equations for an AFM vector and corresponding Fokker-Planck equation for distribution function in the phase space of generalised coordinate and momentum. Thermal noise is modeled by a random delta-correlated magnetic field that interacts with the dynamic magnetisation of AFM particle. We analyse in details a particular case of the collinear compensated AFM in the presence of spin-polarised current. The energy distribution function for normal modes in the vicinity of two equilibrium states (static and stationary) in sub- and super-critical regimes is found. It is shown that the noise-induced dynamics of AFM vector has pecuilarities compared to that of magnetisation vector in ferromagnets.Comment: Submitted to EPJ ST, presented at the 4-th Conference on Statistical Physics, Lviv, Ukraine, 201

Separation of Oligosaccharides from Lotus Seeds via Medium-pressure Liquid Chromatography Coupled with ELSD and DAD

peer-reviewedLotus seeds were identified by the Ministry of Public Health of China as both food and medicine. One general function of lotus seeds is to improve intestinal health. However, to date, studies evaluating the relationship between bioactive compounds in lotus seeds and the physiological activity of the intestine are limited. In the present study, by using medium pressure liquid chromatography coupled with evaporative light-scattering detector and diode-array detector, five oligosaccharides were isolated and their structures were further characterized by electrospray ionization-mass spectrometry and gas chromatography-mass spectrometry. In vitro testing determined that LOS3-1 and LOS4 elicited relatively good proliferative effects on Lactobacillus delbrueckii subsp. bulgaricus. These results indicated a structure-function relationship between the physiological activity of oligosaccharides in lotus seeds and the number of probiotics applied, thus providing room for improvement of this particular feature. Intestinal probiotics may potentially become a new effective drug target for the regulation of immunity

ПРИМЕНЕНИЕ МЕТОДОВ ФЮХТБАУЭРА–ЛАДЕНБУРГА И СООТВЕТСТВИЯ ДЛЯ ОПРЕДЕЛЕНИЯ СПЕКТРОВ СЕЧЕНИЙ СТИМУЛИРОВАННОГО ИСПУСКАНИЯ НЕОДИМОВЫХ ЛАЗЕРНЫХ СРЕД

Rare-earth doped crystals with broad bands of gain spectra are attractive for femtosecond laser applications. Therefore, for this purposes crystals with disordered structure are of great interest. In this article we investigate laser-related spectroscopic properties of new trigonal crystals Nd3+:Ca10K(VO4 )7 (Nd:CKV), Nd3+:Ca9 La(VO4 )7 (Nd:CLaV) и Nd3+:Ca10Li(VO4 )7 (Nd:CLiV). The Füchtbauer-Ladenburg equation and the integral reciprocity method were applied for determination of stimulated emission cross section spectra for Nd3+ ions. The maximum values of emission cross sections and bandwidth (FWHM) near λ = 1,07 μm are 9,33·10 -20cm2 (σ – polarization, Nd:CKV) and 30 nm (π – polarization, Nd:CKV), near λ = 1,35 μm – 1,55·1020cm2 and 50 nm (π – polarization, Nd:CKV). The broad and smooth bands of the gain spectra in the regions near 1,07 and 1,35 μm make it possible to generate ultra short light pulses with duration of about 60 fs (1,07 µm) and 45 fs (1,35  µm) in the mode-locking regime. Для создания лазеров, генерирующих импульсы ультракороткой длительности, представляют большой интерес лазерные материалы с широкими полосами усиления. В этой связи значительный интерес представляют структурно разупорядоченные материалы, в частности новые кристаллические среды, принадлежащие тригональной сингонии Nd3+:Ca10K(VO4 )7 (Nd:CKV), Nd3+:Ca9 La(VO4 )7 (Nd:CLaV) и Nd3+:Ca10Li(VO4 )7 (Nd:CLiV). В данной работе формула Фюхтбауэра-Ладенбурга и интегральный метод соответствия применены для определения спектров сечений стимулированного испускания указанных выше кристаллов на переходах 4 F3/2 → 4 I9/2, 4 F3/2 → 4 I11/2, и 4 F3/2 → 4 I13/2 иона неодима. Максимальные пиковые значения сечений стимулированного испускания и наибольшие спектральные ширины полос в области 1,07 мкм составляют 9,33·10-20 см2 (σ-поляризация, Nd:CKV) и 30 нм (π-поляризация,  Nd:CKV), в области 1,35 мкм – 1,55·10-20 см2 и 50 нм (π-поляризация, Nd:CKV). Полосы стимулированного испускания, а следовательно, и усиления в областях спектра 1,07 и 1,35 мкм являются гладкими и бесструктурными с ширинами, позволяющими получать ультракороткие импульсы света с длительностью  ≈  60 фс (1,07 мкм), ≈ 45 фс (1,35 мкм) в лазерах на исследованных лазерных средах, работающих в режиме синхронизации мод.
