Excess oxygen in La_{2-x}Sr_xCoO_4
Manfred Bucher
The amount of non-stoichiometric oxygen in La_{2-x}Sr_xCoO_{4+y} is calculated from Sr doping, x, and the measured stripe incommensurability 2delta for x = 1/4 and x = 1/3 based on…
Is stripe incommensurability in La_{2-x}Sr_xCoO_4 proportional to doping?
Manfred Bucher
The longstanding notion of stripe incommensurability being proportional to doping, δ(x) ~ x, in lanthanum transition-metal oxides, La_{2-x}Sr_xTmO_4 (Tm = Cu, Ni, Co), is partly bo…
Incommensurability of stripes in La_{2-x}Sr_xNiO_{4+y}
Manfred Bucher
An analytic expression for the incommensurability of static stripes in La_{2-x}Sr_xNiO_{4+y} is given, depending on the hole density n_h = x + 2y. Apart from geometry factors the f…
Unidirectionally shifted shadow arcs in La_{2-x}Sr_xCuO_4 explained
Manfred Bucher
The observed faint shadow arcs, shifted unidirectionally from primary Fermi arcs, are caused by lattice distortion from edge dislocations introduced by cleaving the samples.
Comment on "On the nature of magnetic stripes in cuprate superconductors," by H. Jacobsen et al., arXiv:1704.08528v2
Manfred Bucher
Dynamics reduces the orthorhombicity of magnetic stripes in La_2CuO_4+y. The measured stripe incommensuration can be used to determine the oxygen content of the sample.
Origin of quantum oscillations in doped cuprates
Manfred Bucher
It is proposed that Fermi-surface reconstruction in electron-doped Ln_{2-x}Ce_xCuO_4 (Ln = Pr, Nd) and in hole-doped YBa_2Cu_3O_{6+y} and YBa_2Cu_4O_8 occurs when the Fermi arcs ex…
