Title: Oxide superconductor and manufacture thereof
Inventor: SHIGA SHOJI
IPC: C30B29/22
Filed: 1989-06-14
Abstract: PURPOSE:To obtain an excellent characteristic of critical current density by alternately depositing an oxide superconductor layer and a metal layer as many times as required, by having a slender crystal oriented to a longitudinal direction of the conductor, and by including at least one grain boudary in a perpendicular direction to this. CONSTITUTION:A metal layer 1 and an oxide superconductor layer 2 are alternately deposited in a concentric circle, and a metal coating layer 3 is situated on the periphery. As a metal is distributed in the oxide superconductor layer 2 in a layered form, electric and thermal conductivity are high, whereby a hysteresis loss at the time of quenching and AC electrification is suppressed. As a crystal structure of each oxide superconductor layer 2 partitioned by the metal layer 1 is composed of a crystal grain 6 grown slender in a longitudinal direction of the conductor, a crystalline grain boundary that works as electrification resistance exists in a small number in a direction of electrification, whereby at least one grain boundary is included in a direction perpendicular to the slender crystal grain. A high value of critical current density can thus be obtained.
