摘要：

Using torque magnetometry, we reveal remarkably simple universal behavior of the superconducting (SC) precursor in the cuprates by tracking the nonlinear diamagnetism above T-c in four distinct compounds: single-CuO2-layer HgBa2CuO4+delta, La2-xSrxCuO4 and Bi-2(Sr,La)(2)CuO6+delta, and double-layer Bi2Sr2Ca0.95Y0.05Cu2O8+delta. We find that SC diamagnetism vanishes in an exponential manner, characterized by a universal temperature scale that is approximately independent of compound and T. We discuss the possibility that this unusual behavior signifies the proliferation of SC clusters as a result of intrinsic inhomogeneity inherent to the cuprates.
