✦ Synopsis

The temperature-, the current-, and the frequency dependences of the conduction noise were studied at temperatures where the broadening of the resistive transition under the presence of magnetic field were observed. The rpsult suggests that the broadening is mainly due to the enhancement of the fluctuation of superconductivity in two-dimensional CU02 planes. A sharp peak in the temperature dependence of the noise power was found at. lower temperatures, which is likely to correlate with t.he melting of the flux lat.tice.
