Abstract
We compare results of high-resolution magnetic flux (susceptibility) measurements in very weak magnetic field, performed of three classes of superconductors. They reveal astonishing details of the transition to the superconducting state. Although Pb behaves also on this scale according to BCS predictions, La is more reminiscent of HTS materials, which exhibit anomalous features. We suggest that known structure peculiarities are due to a strong electron-lattice instability and lead to a resonance electron back scattering.
