Description

In this contribution, the spin and charge “stripe” ordering tendencies observed by neutron and x-ray diffraction in La-based cuprate superconductors [1,2] will be discussed with emphasis on magnetic field effects on these correlations [3,4]. In particular, we will relate our new diffraction results [4] with evidence for hole-pockets arising from ARPES experiments conducted at the SIS beamline at SLS [5] and – more generally – will discuss possible implications for the interpretation of high-field quantum oscillation experiments and evidence for Fermi surface reconstruction in cuprates.
