Abstract:

Magnetic nanocomposites are multi-component materials, typically containing nanosized magnetic material to trigger the response to an external stimulus. Up to now, the search for novel nanocomposites has led to the combination of different materials with various types of magnetic particles. In this study, CoFe2O4/ZrO2 nanocomposite was prepared by hydrothermal approach and then structural properties was investigated1.At the first, ZrO2 nanoparticles, Co2+and Fe3+with a mole ratio of 1:2 were dissolved in distilled water. Then Ammonium hydroxide solution was added drop wise to resultant suspension to attain the pH=11 and stirred continuously for 1 h, followed by a hydrothermal treatment at 180◦C for 10h. The products were washed with deionized water and dried in oven at 60◦C2.The characterizations of the synthesized nanocomposite were carried using powder X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR).The XRD and FTIR patterns of the nanocomposite are shown in Fig.1 and Fig.2, respectively.Fig.1 indicates the diffraction peaks situated at, 30.17, 28.175, 50.474, 45.85, 35.125 correspond to (111) , (101) , (110) ,(211) ,(202) planes of ZrO2 and the peaks at 30.42◦, 35.925◦, 57.525◦and 62.875◦ correspond to (220), (311) ,(511) and (440) planes of CoFe2O4 . [2,3]. From figure 2, peaks observed at 501 and 582 cm-1 are due to the Zr–O vibration mode and the absorption bands at 574.76 and 877.57 cm−1 are assigned to the stretching mode of Fe-O and Co-O bands3.
