✦ Synopsis

Pulsed magnetic field loss measurements have been performed on special V3Ga filament superconductors, which are known to have very high critical current densities, and on a Nb3Sn filament superconductor. The dependence of the hysteresis losses on the diffusion heat treatment parameters for the V3Ga layer formation is reported. To analyse the results, the hysteresis losses of hollow superconducting filaments in parallel and perpendicular magnetic fields were calculated. From E.J. Kramer's theory of flux pinning we postulate that, for a given material, upper and lower intrinsic limits of the hysteresis losses are due to the flux line shearing effect. A part of the results was presented at the ICEC 7.
