Abstract
We measured the fluctuating voltage in the vortex state of Bi2Sr2CaCu2Oy in the samples with a Corbino disk geometry, in order to investigate the orig in of the broad-band noise (BBN). The BBN in the noise spectra was found ev en in the Corbino configuration and its behavior was almost similar to that in a platelet geometry reported so far. The broad-band conduction noise ge nerated irrespective of the configurations strongly supports the bulk natur e as its origin. (C) 2001 Elsevier Science B.V. All rights reserved.
