The gel have been heated at 150°C for 3 h, dried, grounded and followed by calcination at 750°C  for 5 h. The X-ray diffraction (XRD) patterns of samples are indexed and well matched with rhombohedral structure (R3c). The samples of Bi&lt;sub&gt;1-x&lt;/sub&gt;Y&lt;sub&gt;x.&lt;/sub&gt;FeO&lt;sub&gt;3&lt;/sub&gt;&lt;sub&gt;,&lt;/sub&gt; (x = 0, 0.06, 0.12) show impuruties of  Bi&lt;sub&gt;25&lt;/sub&gt;Fe&lt;sub&gt;2&lt;/sub&gt;O&lt;sub&gt;39&lt;/sub&gt; in small amount. The decrease intensity in the splitting of (104) and (110) peaks around 2θ = 32° indicates the reduction of the rhombohedral phase transform to orthorhombic phase. The scanning electron microscopy (SEM) shows doping Yttrium reduce particle size. The M-H curve measured with SQUID results saturation magnetization at 60 K of pure (3.36 emu/g) and Y doped (19.54 emu/g), the saturation magnetization at 300 K of  pure (3.11 emu/g) and Y doped (14.73 emu/g).
