  • Superconductive elements and method for producing the same
    Patent number: 4001481
    Abstract: A superconductive element comprising a substrate, at least one face of which is composed of alumina, and a layer of a superconductive compound of the Nb-Al, Nb-Ga, Nb-Al-Ge or Nb-Ga-Al system formed on the alumina face, which exhibits an excellent critical current density in either a low magnetic field or a high magnetic field and simultaneously has a high critical temperature, and in which peeling or cracking is not caused, and a method for preparing such superconductive element comprising the step of vaccum depositing the above-noted superconductive compound on an alumina surface of a substrate.
