    Pylypovskyi, O.V.; Sheka, D.D.; Kravchuk, V.P.; Gaididei, Y. (Физика низких температур, 2015)
    Vortex core reversal in magnetic particle is essentially influenced by a surface anisotropy. Under the action of a perpendicular static magnetic field the vortex core undergoes a shape deformation of pillow- or barrel-shaped ...

    Formation of low frequency harmonics on turbulent distribution in the system of waves on the surface of liquid hydrogen has been studied in the frequency range 1–100 Hz (capillary-gravity waves). It is shown that the geometry ...
