Аннотация: This paper is devoted to the investigation of iron globules that are formed during cooling of the iron-carbon-helium plasma and as a result of destruction of a natural ball lightning. Scanning electron microscopy, X-ray fluorescence, X-ray diffraction, and ferromagnetic resonance investigations were carried out. The magnetization values of the samplers were determined.

Аннотация: The solution of the problem of all-optical (nonmagnetic) confinement of ultracold electron-ion neutral plasma based on selective action on plasma ions with quantum transition J = 1 -> J = 0 of so-called rectified radiation forces in a strong nonmonochromatic light field is suggested. The presented scheme of the three-dimensional dissipative optical trap for plasma allows one to obtain long-lived ultracold plasma with controlled characteristics. The lifetime of the ultracold plasma in such a trap may exceed considerably (by orders of magnitude) the time of free plasma expansion and the lifetime in the (earlier proposed) optical molasses for the ultracold plasma.

Аннотация: Laser cooling and crystallization of electron-ion plasma is studied using the Brownian dynamics simulation technique and taking into consideration the interaction of ions with the electron subsystem. It has been shown that the nonlinear dependence of laser friction force on the velocity of ions has to be taken into account in order to simulate in an adequate manner the cooling dynamics and obtain a correct estimate for minimum temperatures. It has been found that times required for formation of an ordered ionic structure can be much longer than the typical plasma cooling time.

Аннотация: Depletion dynamics of an open system of weakly interacting fermions with two-body random interactions is studied. In this model, fermions are escaping from the high-energy one-particle orbitals, that mimics the evaporation process used in laboratory experiments with neutral atoms to cool them to ultra-low temperatures. It is shown that due to self-thermalization the system instantaneously adjusts to the new temperature which decreases with the course of time.

Exchange bias in nano-ferrihydrite / D. A. Balaev [et al.] // J. Appl. Phys. - 2016. - Vol. 120, Is. 18. - Ст. 183903, DOI 10.1063/1.4967912. - Cited References: 43. - The authors are grateful to M.

Аннотация: We report the results of investigations of the effect of cooling in an external magnetic field starting from the temperature over superparamagnetic blocking temperature TB on the shift of magnetic hysteresis loops in systems of ferrihydrite nanoparticles from ∼2.5 to ∼5 nm in size with different TB values. In virtue of high anisotropy fields of ferrihydrite nanoparticles and open hysteresis loops in the range of experimentally attainable magnetic fields, the shape of hysteresis loops of such objects in the field-cooling mode is influenced by the minor hysteresis loop effect. A technique is proposed for distinguishing the exchange bias effect among the effects related to the minor hysteresis loops caused by high anisotropy fields of ferrihydrite particles. The exchange bias in ferrihydrite is stably observed for particles not less than 3 nm in size or with TB over 40 K, and its characteristic value increases with the particle size. © 2016 Author(s).

Аннотация: Heat capacity and intensive magnetocaloric effect (MCE) in manganites (La1-yEuy)(0.7)Pb0.3MnO3[y=0.2; 0.6] (LEPM) were investigated by means of adiabatic calorimeter. The heat capacity anomaly as well as the values of both the intensive (Delta T-AD) and the extensive (Delta S-MCE) MCE were found to decrease upon increased replacement of La with nonmagnetic Eu. However, because of widening of the MCE peaks, the LEPM compounds show the relative cooling power, RCP/Delta H, comparable to other solid solutions of manganites. Owing to strong effect of Eu -> La substitution on the Curie temperature, LEPM might have potential as the solid state refrigerants in multi-element cooling apparatus operating in a wide temperature range.

Аннотация: Heat capacity measurements were performed for a single crystal wafer of PMN in the temperature range of 170-250 K applying an electric field E = 3.0 kV/cm along the [111] direction. The heat capacity anomalies related to the phase transition at Tc = 210 K upon zero field heating after field cooling and at Tc = 223 K upon field cooling have been found. The results obtained are discussed together with the data of previous studies in the frame of the spherical random bondrandom field model.
