Orientation determination of dynamic stripes in superconducting LCO+O by means of polarized scattering
Previous research from our group revealed a discontinuity of the magnetic fluctuations dispersion in oxygen doped LCO+O, in the limit of vanishing energy transfer. This result was interpreted as an electronic phase separation into two phases, one containing the static stripes, and the associated fluctuations which were not measured, and the second containing the observed magnetic fluctuations. One characteristic that would support this would be a different orientation of the two types of magnetic modulations. In order to answer this question we have already performed polarized neutron scattering on this sample and were able to determine the orientation of the elastic signal. We now propose a method of determining the orientation of the spin fluctuations in the same sample.
