Anomalous doping dependence of the fluctuation-induced diamagnetism in superconductors of YBCO family

A. Lascialfari, A. Rigamonti, L. Romano' +3

SQUID magnetization measurements in oriented powders of Y $_{1 - x}$ Ca $_{x}$ BaCu $_{3}$ O $_{y}$ , with $x$ ranging from 0 to 0.2, for $y \approx 6.1$ and $y \approx 6.97$ , have bee…

Magnetic field dependence of the superconducting fluctuation contribution to NMR-NQR relaxation

P. Mosconi, A. Rigamonti, A. A. Varlamov

The dependence of the Maki-Thompson (MT) and of the density of states depletion (DOS) contributions from superconducting fluctuations (SF) to NMR-NQR relaxation is derived in the f…
