Original Kurzfassung:
Eu0.8Sr0.2FexCo1−xO3−z CMR perovskites with different iron concentrations (x= 0, 0.025, 0.075, 0.15, 0.3) were investigated by X-ray diffraction, AC magnetic
susceptibility, magnetotransport, as well as 57Fe and 151Eu Mössbauer spectrometry. The valence state of europium ions was found to be trivalent, independently of the iron concentration. 57Fe Mössbauer spectra and magnetic susceptibility of the investigated
perovskites presented complementary results for the magnetic transitions.
