Abstract A theoretical analysis for the anomalous low frequency noise enhancement with frequency dependence 1 f 2 which was recently measured in micropatterned YBaCuO thin films was carried out. A generalization of the random fluctuation model we developed earlier led to plausible activation energies and accounted simultaneously for the frequency, temperature, and magnetic field dependence of the noise spectral power. In this approach the defect density functional D( n ) where n is the density… CONTINUE READING
