Abstract:
In this thesis, Iron rich permalloy FexNi1-x nanoparticles were fabricated using a low temperature wet chemistry method involving the hydrothermal growth of the nanoparticles. The Fe-Ni alloy fabricated and characterized of the tree nanoparticles, Fe0.5Ni0.5, Fe0.625Ni0.375 and Fe0.83Ni0.17 were studied by X-Ray Diffraction (XRD), Scanning Electron Microscopy (SEM) and Vibrating Samples Magnetometer (VSM). After the initial formations, the three Fe-Ni nanoparticles were annealed at 200 °C, 400 °C and 600 °C in air for 1 hour. The XRD showed that all three NiFe2O4 nanoparticles had a bcc structure. The positions of the (220), (311), (222), (400), (422), (511), (440) and (533) lines can be index to the lines of the cubic structure (JCPDS No. 54-0964).
The positions of peaks yielded the following lattice constants. SEM images showed that the nanoparticles had spherical shapes; the spherical shapes of the FeNi nanoparticles become more pronounce as the nickel content increased. The images for Fe0.5Ni0.5 nanoparticles showed well-formed spherical particles. While some of the nanoparticles observed in Fe0.83Ni0.17 and Fe0.625Ni0.375 were spherical like, they were not as spherical like those of the Fe0.5Ni0.5. They had distorted hemispherical surfaces. They also appeared to be smaller. The magnetic properties of the three Fe-Ni nanoparticles were superparamagnets. The heat treatments cause the work needed to the flip the spin (coercivity Hc) to increase and the values of the saturation magnetizations to fluctuate. The saturation magnetizations MS of each magnetic nanoparticle decreases as the amount of Ni increases, Ms (Fe0.5Ni0.5) > Ms (Fe0.625Ni0.375).> Ms (Fe0.83Ni0.375). This is to be expected since the Ni component of the nanoparticles has a lower magnetic moment than the Fe component.
