f-α noise in NbSe3

摘要: The authors have measured the voltage noise of NbSe3 samples in nonlinear state as a function frequency for temperatures below lower charge density wave formation temperature. They find that over broad conditions electric fields and power spectrum follows f- alpha dependence with approximately 0.8. interpret broad-band due either to mixing radiofrequency radiated by domains which form lattice, or alternatively dynamics kinks-antikinks along chains.
