Keywords:
Multiferroic, BiFeO3, Microwave absorption, DopedAbstract
Polycrystalline Bi1-xYxFeO3 with x = 0, 0.06, and 0.12 wt%  have been synthesized by sol–gel autocombustion method. 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 Bi1-xYx.FeO3, (x = 0, 0.06, 0.12) show impuruties of  Bi25Fe2O39 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). Reflection Loss (RL) of of Bi1-xYxFeO3/Silicon Rubber composite increase with optimum value of -37.23 dB at 10.85 GHz.
