  • Attainable electron energy in diode with plasma cathode at the given voltage 
    Ostroushko, V.; Pashchenko, A.; Pashchenko, I. (Вопросы атомной науки и техники, 2019)
    It is considered an acceleration of electrons in a one-dimensional interval, part of which is filled by ions initially compensated by electrons. For the stages of forward motion and backward motion of a part of electrons, ...
  • Effect of electron collisions with residual neutral gas on characteristic oscillation frequencies in systems of electron flows with a virtual cathode 
    Manuilenko, O.; Novikov, V.; Pashchenko, A.; Pashchenko, I.; Shapoval, I.; Yuferov, V. (Problems of Atomic Science and Technology, 2023)
    A system of the hydrodynamic equations describing the electron flows in a diode with a virtual cathode is considered. Collisions are considered by introducing the corresponding braking force into the equations of motion. ...
  • Electron flow dynamics in resistive gap 
    Pashchenko, A.; Ostroushko, V. (Вопросы атомной науки и техники, 2017)
    It is considered the evolution of electron flow in the short-circuited gap with taking into account of the braking force proportional to velocity. The linear analysis of the stationary states stability is made. For the ...
  • Electron flow stability in the gas filled diode 
    Pashchenko, A.; Ostroushko, V. (Вопросы атомной науки и техники, 2017)
    For the electron fow in the short-circuited diode filled with gas, with taking into account the braking force proportional to velocity, the stationary modes and their linear perturbations are considered. The equation for ...
  • Magnetic and magnetocaloric properties of the La₀.₉–xAgxMn₁.₁O₃ compounds 
    Zubov, E.; Pashchenko, A.; Nedelko, N.; Radelytskiy, I.; Dyakonov, K.; Krzyżewski, A.; Ślawska-Waniewska, A.; Dyakonov, V.; Szymczak, H. (Физика низких температур, 2017)
    The influence of Ag⁺ ions and Mn non-stoichiometry on the magnetic properties and magnetocaloric effect in the La₀.₉–xAgxMn₁.₁O₃ compounds has been studied. The Ag⁺ ions content substituting for trivalent lanthanum ions ...
  • Nanoparticles effect on magnetic and transport properties of (La₀,₇Sr₀,₃)₀,₉Mn₁.₁O₃ manganites 
    Dyakonov, V.; Slawska-Waniewska, A.; Kazmierczak, J.; Zubov, E.; Myronova, S.; Pashchenko, V.; Pashchenko, A.; Shemjakov, A.; Varyukhin, V.; Prilipko, S.; Mikhaylov, V.; Piotrowski, K.; Kravchenko, Z.; Iesenchuk, O.; Szytula, A.; Bazela, W.; Szymczak, H. (Физика низких температур, 2009)
    We report on the magnetic and transport thermal measurements of nanosize (La₀,₇Sr₀,₃)₀,₉Mn₁.₁O₃ manganite. The nanoparticles were synthesized with use of co-precipitation method at different (800, 900 and 950 °C) temperatures. ...
