N2 - A La0.7Ca0.3Mn0.5Fe0.5O3 (LCMFO) ceramic sample was produced using conventional solid-state reactions. According to the X-ray diffraction data, the obtained sample has an orthorhombic space group Pnma (a = 5.482(2) Å, b = 7.739(3) Å, c = 5.446(3) Å). Magnetic properties of the obtained sample were studied by 57Fe Mössbauer spectroscopy in the temperature interval of 77–423 K. All spectra recorded at room temperature exhibit the presence of trivalent Fe. Mössbauer spectra of the LCMFO sample show the presence of two intensive components: a paramagnetic doublet and a magnetic sextet, and several weak magnetic sextets. Within the investigated temperature range, phase separation and coexistence of a paramagnetic matrix and a phase of nano-sized antiferromagnetic clusters both below and above TN were found.
