【 摘 要 】

In the present work, we have synthesized Y-type hexaferrite Ba2Mg2Alx/2Crx/2Fe12-xO22 (x = 0.0, 0.5, 1.0) using solution gel method. The structural and magnetic properties have been investigated using XRD, FTIR and VSM.X-ray study shows that grain size lies in nano range. Presence of two prominent peaks near 550-600 cm-1 to 500-600cm-1 in FTIR indicates the formation of hexaferrite. From VSM analysis, It is found that with increasing the amount of co-dopants (Al - Cr) the saturation magnetization, retentivity and increases for x = 0 andx - 0.5 it was observed that coercivity is zero which indicates that material is super-paramagnetic in nature.
