I n s i t u growth of superconducting Nd-Ce-Cu-O thin films

Abstract
Superconducting Nd‐Ce‐Cu‐O thin films were epitaxially grown on SrTiO3 (100) by activated reactive evaporation. As‐grown films showed the metallic temperature dependence of the resistivity and superconducting transition at 12.5 K (R=0). The remarkable parallel shift of the onset temperature of the resistive transition in the magnetic fields was observed. Ginzburg–Landau coherence lengths along the c axis and in the basal plane are 7 and 96 Å, respectively.
