摘要：

10% Co-doped BiFeO3 nanoparticles have been prepared by a low temperature sol-gel method. XRD result shows that particles are single phase in nature and crystallizes in distorted perovskite structure ( space group R3c) with average particle size of 60 nm. Room temperature ferromagnetism along with saturation magnetization of about 2.24 emu/g and high coercive field of 1260 Oe has been found by VSM measurements. Mossbauer data can be fitted with single magnetic sextet of isomer shift about 0.35 mm/s and hyperfine field about 49 T indicating Fe3+ nature of Fe atom present in Co-doped BiFeO3 nanoparticles.
