Measurement of unique magnetic and superconducting phases in oxygen-doped high-temperature superconductors La<sub>2-x</sub>Sr<sub>x</sub>CuO<sub>4+y</sub>
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)

Driven vortices in 3D layered superconductors: Dynamical ordering along the c-axis
We study a 3D model of driven vortices in weakly coupled layered
superconductors with strong pinning. Above the critical force , we find a
plastic flow regime in which pancakes in different layers are uncoupled,
corresponding to a pancake gas. At a higher , there is an ``smectic flow''
regime with short-range interlayer order, corresponding to an entangled line
liquid. Later, the transverse displacements freeze and vortices become
correlated along the c-axis, resulting in a transverse solid. Finally, at a
force the longitudinal displacements freeze and we find a coherent solid
of rigid lines.Comment: 4 pages, 3 postscript figure
