In this paper, we have studied the crystal structure of strontium-substituted manganite and ytterbium ferromanganites Yb0.82Sr0.18Mn1 – xFexO3 (x = 0–0.2) by using X-ray diffraction analysis. Magnetic microstructure has been studied by electron paramagnetic resonance and nuclear gamma-resonance (Mössbauer) spectroscopy. We have observed phase separation in the ceramics for antiferromagnetic, superparamagnetic, and ferromagnetic phases.
