Abstract
The flux noise power spectrum has been measured between 20K and 31K (T{sub c}{approx_equal} 30K), under d.c. fields up to 5.5 Oe. It is shown that dissipation is mainly due to intergrain currents. At low temperatures, the 1/f character of the fluctuations power spectrum supports the existence of a transition to a glassy state below 27K. 8 refs.; 2 figs.
