| Abstract: | he stability of the horizontal and vertical oscillations of anisotropic high-Tc superconductors in an inhomogeneous magnetic field has been investigated.The oscillation amplitude of the levitated HTSC has been measured as a function of the frequency and amplitude of the external force. For the first time, the resonance of the oscillation amplitude has been observed in the frequency range from 20 to 40 Hz.This behavior is described with the general theory of oscillation. |
