摘要: Abstract The out-of-plane resistivity ( ρ c ) has been measured in under-doped La 2− x Sr CuO 4 under pressure to investigate the nature of superconducting transition. antiferromagnetic insulating sample with =0.020 did not show superconductivity even pressure. However, non-superconducting samples =0.035 and 0.045, an appreciable but incomplete drop was observed lowering temperature increasing suggests existence intrinsic phase separation or inhomogeneity around ∼0.05.
