ABSTRACT
Layer-by-layer pulsed-laser deposition has been used to grow ultrathin superconducting (Ba[sub 0.9]Nd[sub 0.1])CuO[sub 2+x]/CaCuO[sub 2] artificial structures with various thicknesses of the two constituent layers. Superconductivity was observed in the ultrathin structure consisting of a single CaCuO[sub 2] superconducting block sandwiched between two (Ba[sub 0.9]Nd[sub 0.1])CuO[sub 2+x] blocks. The results obtained allowed an experimental demonstration of the currently accepted structural model for high T[sub C] superconductivity, which requires the presence in the same structure of two blocks with different functional properties: the superconducting infinite layer block and the nonsuperconducting charge reservoir block. © 2001 American Institute of Physics.
