Claim:
1. A method of forming a superconductor, the method comprising exposing a layer disposed on a substrate to an oxygen ambient; and selectively annealing a portion of the layer using a laser beam to form a superconducting region within the layer, wherein after the selective annealing, the superconducting region comprises superconductor material having a preferred crystallographic orientation in which the c-axis of crystallites are arranged perpendicularly to the plane of the tape in preference over other possible orientations, and wherein a first region of the layer disposed outside the portion of the layer does not comprise a superconductor material having the preferred crystallographic orientation in which the c-axis of crystallites are arranged perpendicularly to the plane of the tape in preference over other possible orientations, the first region not being selectively annealed by the laser beam.
