The structural properties of a magneto-dielectric composite based on the polycrystalline phases (Cr0.75Fe1.25O3) CRFO100 and (Fe0.5Cu0.75Ti0.75O3) FCTO100, synthesized by the mixed oxide solid-state reaction methodology, have been investigated in this paper. The constituent phases, as well their composite series (Cr0.75Fe1.25O3)[W]–(Fe0.5Cu0.75Ti0.75O3)[100−W], for W = 0, 17, 34, 50, 66, 83 and 100, were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), energy-dispersive X-ray spectroscopy (EDXS), and 57Fe Mössbauer spectroscopy techniques. The identification and subsequent refinement of XRD data revealed for CRFO100 and FCTO100 trigonal and cubic structures, respectively. The Mössbauer spectra related to the composites signalize a probable paramagnetic doublet due to FCTO100 phase, and a magnetic sextet due to CRFO100 phase, both associated with Fe3+ in octahedral coordination.
