Abstract:Emergence of memory devices based on magneto-electric coupling leads us to
investigate the dielectric and magneto-dielectric properties of U-type
hexaferrites. (Ba1-3xSm2x)4Co2Fe36O60 ceramics, where x = 0.0-0.25, with the
interval of 0.05, have been produced via auto combustion method and
sintering at 1200?C. Every sample has an R?3m symmetric hexagonal
structure, according to the XRD study. The samples with lower Sm content,
i.e. 0.0 < x < 0.15 have better magnetic properties than the… Show more
