As-grown superconducting MgB2 thin films were deposited by pulsed laser deposition on magnesium oxide and sapphire substrates. Starting from a non-stoichiometric, Mg and B mixed-powder target, we were able to grow the superconducting phase during the film deposition, without any further annealing process. So far, samples grown in the...

We present paraconductivity measurements on YBCO thin films obtained by means of pulsed laser ablation. The films, grown under different oxygen pressures, exhibit critical temperatures ranging from 81 to 92 K. The excess conductivity has been analyzed in order to study the critical phenomena. We observe the Lawrence-Doniach crossover and, at...
