Abstract
A superconducting device and method of making in which a superconducting YBaCuO layer is laser deposited on a SrTiO.sub.3 or similar substrate such that the c-axis of the YBaCuO layer is vertically aligned with that of the substrate. A non-superconducting layer of PrBaCuO or MgO is laser deposited on the superconducting layer and another superconducting YBaCuO layer is laser deposited on the non-superconducting layer with the c-axes of all the layers being aligned. Contacts are applied to the two superconducting layers to form a junction device across the non-superconducting layer, which acts as a barrier layer.
