Flicker-noise spectrum in weak-links-containing superconductors
arXiv:cond-mat/9905363
Abstract
Low-frequency magnetic noise spectrum is calculated within the superconductive glass model. The model predicts the existence of both white noise and flicker-like noise f^{-z} with z strongly dependent on applied magnetic field and temperature. It is shown, in particular, that z increases with field from 0.5 to 1, and that in the critical region (near T_{c}(H)) the 1/sqrt{f} law should prevail in the noise spectrum.
