Query: On amplitude oscillation of vibrations of strongly anisotropic
  high-temperature superconductors of BiPbSrCaCuO system   Effect of oscillations of the vibration amplitude of cylindrical sample
suspended by a thin elastic thread and vibrating in a transverse magnetic field
and containing 2D quasi-two-dimensional vortices (pancakes), was observed in
the strongly anisotropic high-$T_{c}$ superconductor of
$Bi_{1.7}Pb_{0.3}Sr_{2}Ca_{2}Cu_{3}O_{y}$ system.
