Abstract:
A method of manufacturing a superconducting ceramic material, said method including a step of forming a superconducting material from a mixture prepared in accordance with the stoichiometric formulae of (A.sub.1-x B.sub.x).sub.y Cu.sub.z O.sub.w, where A is one or more elements selected from Group IIIa of the Periodic Table, B is one or more elements selected from Group IIa of the Periodic Table, and x=0-1, y+2-4, z=1-4 and w=4-10, said mixture being heated in an oxidizing atmosphere at 500.degree. C. to 1200.degree. C. during said forming step under application of a magnetic field having a strength not lower than 500 Gauss such that a crystalline structure of the material is oriented in accordance with the applied magnetic field.
