Alternative approach to the hysteresis of transport current in Bi-based tapes
Nálevka, Petr ; Jirsa, Miloš ; Koblischka, M. R. ; Pan, V. M. ; Dew-Hughes, D. ; Huang, S. L.
The induced critical currents and the reversible magnetic moment were studied in Bi-based samples prepared by different technologies, in a wide range of temperatures and external magnetic fields.
Chracterisation of the magnetisation hysteresis in RE-123 superconductors by exponentially decaying and power-law functions
Jirsa, Miloš ; Koblischka, M. R. ; Higuchi, T. ; Murakami, M.
The fully developed fishtail shape of the magnetization hysteresis loops in untwined RE-123 bulk materials is well characterized by the logarithmic pinning potential U(j) in frames of the thermally actived pinning process.
