“…Large variations in the saturation magnetization, however, could be due to the presence of impurity phases in some prepared samples. Further, modifications of the properties of Y-type hexaferrites by substitutions for Fe 3+ ions were also reported [12,35,49,51,94,[96][97][98][99][100][101][102][103]. However, research work devoted to the effects of such substitutions in Y-type hexaferrites is relatively limited.…”

Abstract. The present study is concerned with the fabrication and characterization of Me2Y substituted hexaferrites, Ba2Me2Fe12-xTxO22 (Me = Co 2+ , Mg 2+ , and Cr 2+ , and T = Fe 3+ , and Ga 3+ ). The samples were prepared by the conventional ball milling technique and sintering at 1200° C. The effect of the choices of Me and T ions on the structural and magnetic properties of the hexaferrites were investigated. XRD patterns, magnetic parameters, and Mössbauer spectra of the Co2Y were consistent with a single phase Y-type hexaferrite. However, the CoCr-Y sample was found to be dominated by the Y-type hexaferrite, and M-type and BaCrO4 minority phases were observed in the XRD pattern of the sample. The small increase in saturation magnetization from about 34 emu/g up to 37.5 emu/g was therefore attributed to the development of the M-type phase. On the other hand,
