Pulsed laser deposition of superconducting REBa2Cu3O7-x thin films

Superconducting thin films of REBa2Cu3O7-x (RE=Sm, Eu, Gd) were deposited by Pulsed Laser Ablation on strontium titanate substrates at different substrate temperature and reduced oxygen pressure. The resistivity vs. temperature measurements show the onset and the offset of the superconducting transition between 95K and 70K. For all the investigated Rare Earths we find a substrate temperature value for which the grown film has the offset of the superconducting transition above 90K.
