Original Kurzfassung:
In this paper we present 57Co emission Mössbauer and AC magnetic susceptibility studies of La0.8Sr0.2CoO3-d perovskite. The observed coexistence of paramagnetic and magnetic subspectra in the 57Co emission Mössbauer spectra, as well as the difference of their isomer shifts
support the existence of electronic phase separation in this perovskite, in good agreement with the double exchange based cluster model.
