Abstract
Motivated by recent transport and magnetization measurements in Bi2Sr2CaCu2O8 samples [B. Khaykovich, D. T. Fuchs, K. Teitelbaum, Y. Myasoedov, E. Zeldov, T. Tamegai, S. Ooi, M. Konczykowski, R. A. Doyle, and S. F. W. R. Rycroft, Phys. Rev B 61, R9261 (2000)], we present a simple macroscopic model describing effects of inhomogeneous current distribution and shear in a layered superconductor. Parameters of the model are deduced from a microscopic calculation. Our model accounts for the strong current nonlinearities and the reentrant temperature dependence observed in the experiment.
