Magnetic moment of welded HTS samples: dependence on the current flowing through the welds [PDF]
Supercond. Sci. Technol., Vol.15, No.9 (2002) pp.1353-1356., 2002 We present a method to calculate the magnetic moments of the high-temperature superconducting (HTS) samples which consist of a few welded HTS parts. The approach is generalized for the samples of various geometrical shapes and an arbitrary number of welds. The obtained relations between the sample moment and the density of critical current, which flows
