Critical state model with anisotropic critical current density

Journal of Physics: Condensed Matter, 2003
Analytical solutions of Bean's critical state model with critical current density Jc being anisotropic are obtained for superconducting cylindrical samples of arbitrary cross section in a parallel geometry. We present a method for calculating the flux fronts and magnetization curves.

Magnetisation hysteresis and critical current density

Physica C: Superconductivity, 1989
Abstract The hysteresis in magnetisation is extensively used to infer the critical current density of high T c superconductors. We use calculated magnetisation curves, obtained analytically for two particular forms of J c ( H ), to examine the validity of the method currently used. We show that this method is valid only at large fields, and that

Intrinsic critical current densities of PbMo6S8

Physica B: Condensed Matter, 1990
The high upper critical field B c2 is now demonstrated to be an intrinsic property of the PbMo 6 S 8 (PMS) Chevrel phase compound. However lower values of B c2 determined using measurements based on macroscopic screening currents (like ac susceptibility and critical current densities), suggest that the granular nature of this superconductor may ...

Critical current density of the whiskers

Journal of Physics: Condensed Matter, 1998
The whiskers with 2212 phase have been grown out by annealing a melt-quenched plate in a stream of gas at for 121 hours. Temperature dependences of the magnetic susceptibility (-T) and the critical current density have been measured. The transition point of the whiskers is 76.2 K, and the value is at 63.4 K, zero magnetic field.

Critical Current Density and Microstructure of YBa2Cu4O8

Journal of Applied Physics, 1991
We investigated the intragranular critical current density Jc in YBa2Cu4O8 prepared by two routes with different oxygen pressures. A relationship between the Jc’s and the microstructures observed by transmission electron microscopy is discussed. The magnitude of Jc for the low oxygen processed sample is higher by a factor of 5 than that for the high ...

Critical current densities in superconducting materials

Sadhana, 2003
We discuss recent research in the area of critical current densities (JC) in superconductors. This shall cover recent work on newly discovered superconductors, as well as on the magnetic-field dependence ofJc.
