Abstract

We have found a little suppression of superconductivity at x = 0.21 in La2-xSrxCuO4 single crystals and, moreover, a giant suppression of superconductivity at x = 0.21 through the 1 % substitution of Zn for Cu. In the Zn-substituted La2-xSrxCu1-yZnyO4 single crystal with x = 0.21 and y = 0.01, the resistivity exhibits an upturn at low temperatures below ∼80 K. These results suggest that the dynamical stripe correlations of spins and holes are pinned by a small amount of Zn at x = 0.21, leading to a static stripe order and the giant suppression of superconductivity, as in the case of x = 0.115.
