Peak Effect of Jc and Nonlinear E-J Characteristies of High-Tc Superconductors
arXiv:cond-mat/0107044
Abstract
The critical current density Jc in high-Tc superconductors (HTS) often shows a maximum at field far above the self-field. We study this peak effect(PE) with the nonlinear I-V response of type-II superconductors and find analytical equation of Jc in the dependence of filed and temperature. Theis equation is compared with some experimental data of R-Ba-Cu-O single crystals with fair agreement.
