dc.description.abstractEffect of nickel doped iron oxide nanoparticles on their magnetic susceptibility and morphological properties has been investigated. The iron oxide nanoparticles were prepared from Logas natural sand using ball milling method for 3 stages. The sand sample was processed with Iron Sand Separator (ISS) and NdFeB Magnet in order to separate between iron non iron oxide particles prior to ball milling. The first stage milling was done well for 3 hours using 18 balls with diameter of 1.5 cm. The product is called BM 1. The BM 1 product was processed using NdFeB magnets in order to separate between iron non iron oxide particles, then for the second stage of ball milling using the same milling parameters for 15 hours, then the product is called the BM2. The BM2 was processed again using NdFeB magnet and the ball milling process starts again for 102 hours with variations of 18 balls with 1.5 cm diameters and 50 balls with 0.5 cm diameters. The product is then called the BM 3. The BM 3 product was divided into 5 parts in equal weight and doped using Nickel (Ni) nanoperticles with a concentration of (0; 5; 10; 15 and 20) wt% for 20 hours using ball milling. Magnetic susceptibility was measured using Pasco PS-2162 Magnetic Probe as a function of currents of 100 mA, 200 mA, 400 mA, 600 mA, and 800 mA. The results of the magnetic susceptibility increased with the addition of nickel concentration. The size and morphology of the iron oxide nanoparticles were characterized by Scanning Electron Microscope (SEM) for 3 selected concentrations of (0;5 and 10) wt%. The results show that the particle size becomes smaller, that is 0.061μ m, 0.047 μm and 0.042 μm as the nickel concentration increases.en_US
