Query: Direct proof of unique magnetic and superconducting phases in
  superoxygenated high-Tc cuprates   We present a combined magnetic neutron scattering and muon spin rotation
study of the nature of the magnetic and superconducting phases in
electronically phase separated La(2-x)Sr(x)CuO(4+y), x = 0.04, 065, 0.09. For
all samples, we find long-range modulated magnetic order below T_N ~ T_c = 39
K. In sharp contrast wit oxygen-stoichiometric La(2-x)Sr(x)CuO(4), we find that
the magnetic propagation vector as well as the ordered magnetic moment is
independent of Sr content and consistent with that of the 'striped' cuprates.
Our study provides direct proof that superoxygenation in La(2-x)Sr(x)CuO(4+y)
allows the spin stripe ordered phase to emerge and phase separate from
superconducting regions with the hallmarks of optimally doped
oxygen-stoichiometric La(2-x)Sr(x)CuO(4).
