【 摘 要 】

The Co-Ni ferrites with general formula NiXCo1-XFe2O4(where X=0.0, 0.1, 0.15, 2, 0.4) were prepared by Sol-gel auto combustion method. X-ray, FTIR and EXAFS measurement were carried out. Extended X ray Absorption Fine Structure (EXAFS) spectra have been recorded at the K-edge of Fe using the Dispersive EXAFS (DEXAFS) beam line-8 Indus-2 synchrotron radiation source RRCAT, Indore, India. The EXAFS data have been analysed using the computer softer Athena. These have been used to determine the Bond length in these ferrites with help of four different methods, namely, Levy's, Lytle's and Lytle, Sayers and stern's (LSS).
