摘要： A high-T.sub.c superconductor contact unit having low interface resistivity is disclosed, as is a method for making the unit. An inert metal is deposited on the surface of the superconductor, which surface is preferably non-degraded, to form a unit with the surface of the superconductor, and where temperatures as high as 500.degree. C. to 700.degree. C. can be tolerated, the unit is oxygen annealed to establish a still lower surface resistivity between the surface of the high-T.sub.c superconductor and the inert metal, including a low surface resistivity of about 10.sup.-10 .OMEGA.-cm.sup.2 at high-T.sub.c superconductor operating temperatures. The superconductor is a metal-oxide superconductor, and may be rare earth, thallium, or bismuth based.

摘要： A low resistivity contact to a high-Tc superconductor is made by forming a contact pad on the surface of an abraded or freshly prepared superconductor by depositing an inert metal on the surface so that a surface resistivity between the surface of the high-Tc superconductor and the pad is established of less than about 1000.mu..OMEGA.-cm.sup.2 at high-Tc superconductor operating temperatures.

摘要： Method and apparatus are disclosed utilizing superconducting elements with extended strain operating range capabilities. The superconducting element is formed from a crystalline compound superconductive material that does not exhibit appreciable critical current degradation in the presence of high elastic strains imposed on the element. Such a crystalline compound superconductive material is selected from materials in the B1 and C15 crystal structure classes. The thus formed superconducting element is particularly useful in electromagnets requiring high magnetic fields for operation in the intended manner.
