Query: On the microscopic origin of the magneto-electronic phase separation in
  Sr doped LaCoO3   The nanoscopic magneto-electronic phase separation in doped La1-xSrxCoO3
perovskites was studied with local probes. The phase separation is directly
observed by M\"ossbauer spectroscopy in the studied doping range of 0.05 <= x
<= 0.25 both at room-temperature as well as in the low temperature magnetic
phase. Extended with current synchrotron based X-ray spectroscopies, these data
help to characterize the volume as well as the local electric and magnetic
properties of the distinct phases. A simple model based on a random
distribution of the doping Sr ions describes well both the evolution of the
separated phases as well as the variation of the Co spin state. The experiments
suggest that Sr doping initiates small droplets and a high degree of doping
driven cobalt spin-state transition, while the Sr-free second phase vanishes
rapidly with increasing Sr content.
