Abstract
In a fabrication method of a MgBsuperconducting tape and wire by filling a tube with a MgBsuperconducting powder and forming it into a tape or wire, a fabrication method of a MgBsuperconducting tape (and wire) which is characterized by using a MgBsuperconducting powder having a high critical current density (J) owing to its lowered crystallinity and having potential for excellent grain connectivity as the MgBsuperconducting powder. Provided are a fabrication method of a MgBsuperconducting tape and wire which can fabricate a MgBsuperconducting tape and wire having a level of Jsufficiently high for practical applications and homogeneous quality throughout its length by an ex-situ process employing a material of the composition suitable for its working environment as the sheath material, and a MgBsuperconducting tape and wire thereby fabricated.
