Oscillations of the magnetization of oriented polycrystalline samples of the highly superconductor õ÷ÁÇóÉÚï;-^ have been measured at low temperatures (4.2 K) in magnetic fields up to 300 T. The magnetic fields were generated by an MK-1 implosion magnetic-field generator through compression of magnetic flux by a cylindrical detonation wave. Fourier analysis of the magnetization signals in fields B>Bc2 reveals oscillations with frequencies of 3.8, 10, 13, and 20 kT. © 1995 American Institute of Physics.
