Abstract: In this article, structure and magnetic properties of nano magnetic Fe3O4 (magnetite) nanoparticles functionalized polyvinyl alcoholic (PVOH) have been investigated by X-ray diffraction (XRD), Vibrating sample magnetometer (VSM) and Mossbauer Spectroscopy (MS) for use in biosensor applications. XRD showed an average of cluster sizes using Debye–Scherrer formula are between 10-13 nm. The magnetization data at room temperature shows weak hysteresis loops and the isotherms of the magnetization curves indicate that superparamagnetism superimposed on the paramagnetic behavior exists in all coated samples. The paramagnetic contribution in coated samples was found to perfectly fit a Langevin equation, with an average number of magnetic dipole moments around 20 Bohr magnetons. The results of MS showed that all magnetic components corresponding to iron oxide particles in polymer spectrum split into a number of sextet separated by about 10-35 T. The line width, relative intensity and the values of the hyperfine fields and isomer shifts for the magnetic components of the samples are estimated. It was found that only the Fe3O4 sample is suitable for practical medical applications such as, drug delivery systems and to design artificial muscles due to its sufficiently high value of saturation magnetization and attraction to magnet ability.


Keywords: Nano magnetic Fe3O4 nanoparticles, X-ray diffraction, Debye–Scherrer formula, Vibrating sample magnetometer, Mossbauer Spectroscopy, Langevin equation.
