“…This is probably due to the competition of the stripe phase formation near this concentration. Indeed, we have observed a clear competition between stripe phase superconductivity and 30 K transition in a series of wellprepared stripe phase samples [18]. However, while the sharp single superconducting transitions are easily understood in terms of our model, the anomalous drop of Meissner signal at x = 1/9 seems to be very unusual.…”

A series of high-quality under-doped La 2-x Sr x CuO 4 superconductor crystals with x = 0.063 ~ 0.125 were prepared by traveling-solvent floating-zone (TSFZ) technique. We found by dc magnetic measurements that, in this series of crystals, the superconducting transition was quite sharp in the vicinity of the hole densities of x = 1/16 and x = 1/9 while it was much broader away from these two 'magic numbers', and the Meissner fraction showed a remarkable minimum near x = 1/9. We concluded that these phenomena are reflections of intrinsic properties of this cuprate system. Our observations are discussed in light of recently proposed composite charge model together with charge inhomogeneity and electronic phase separations.
