Abstract

It is shown that in a granular superconductor magneto-thermal oscillations precede a series of subsequent flux jumps. We study these oscillations experimentally in three YBCO samples at temperatures 3K <T <7K and field sweep rates 10 G/s <Ḃe< 45G/s. We find that the frequency of the oscillations is a linear function of the magnetic field sweep rate and is inversely proportional to the square root of the heat capacity.
