Ceramic composites based on yttrium iron garnet (YIG) and barium titanate (BT) (30%wt YIG/70%wt BT) were prepared by two sol-gel methods and a coprecipitation route. The impact of processing routes on dielectric and magnetic properties was investigated. X-ray diffraction (XRD) data combined with scanning electron microscopy (SEM) observations reveal the presence of both components and a good dispersion of YIG particles into the BT matrix. Ferrimagnetic behavior is observed in all composites, regardless of the preparation method. Ferroelectricity at room temperature was confirmed by Raman spectroscopy and dielectric measurements only in composites prepared by coprecipitation
