Numerical prediction of superconducting critical current density of Bi-2212 single crystal by heavy ion irradiated with fluxoid dynamics method
1999
Abstract The numerical method was developed to simulate the fluxoids' behavior in high T c superconductor Bi-2212. Using this method, the critical current density J c , in the function of the pinning centers concentration and applied magnetic field has been calculated. To verify the validity of the method, the numerical results of J c were compared with the experimental data. Then, J c for an artificial lattice distribution of pinning centers was calculated, and the effect of the distribution of pinning centers on J c was considered.
