The fabrication of long silver-sheathed oxide superconducting tapes by the powder-intube technique tends to lead to non-uniformity in the core thickness during mechanical deformation and densification. This non-uniformity restricts current flow and reduces the critical current density. Using a simpl
Critical current density and its history effect in Bi-based high T c superconducting tapes were measured using an a.c. inductive method with various magnetic fields and temperatures. A rapid decrease in the critical current density with increasing temperature and the history effect were observed in
Buckingham and Fairbank s describe extremely accurate measurements of the specific heat of liquid helium which show that the 2 transition is not of second order, the specific heat undergoing a logarithmic infinity superposed as a step discontinuity of -5.2 J/g/deg.K. The logarithmic infinity is too
An extended critical state model which includes the effects of bulk critical current density, equilibrium magnetization and surface barrier is developed for the magnetization of superconductors. The equilibrium magnetization and surface barrier are modelled by an applied field dependent surface supe
