Abstract
At frequencies 100 KHz and 5 MHz the measurements of the amplitude dependent damping and modulus defect in lead of various purities in the normal and superconducting states are carried out. It is found, that the effect of the N-S transition appears different for the amplitude dependent damping and modulus defect, this difference being dependent on the purity of the specimens used and frequency of the measurements. The results obtained are discussed in terms of the model, taking into account the influence of viscous drag of the dislocations upon the amplitude dependent damping and modulus defect.
