Precursor superconducting effects in the optimally doped YBa${}_2$Cu${}_3$O${}_{7-\delta }$ superconductor: the confrontation between superconducting fluctuations and percolative effects revisited

I. F. Llovo, J. Mosqueira, C. Carballeira +1

The confrontation between the superconducting fluctuations and percolation effects as the origin of the in-plane paraconductivity in cuprate superconductors was earlier addressed a…
