dc.description.abstractMagnetic susceptibility and morphological properties of iron oxide nanoparticles from the natural sand of the Ampalu beach-Pariaman-West Sumatra prepared using ball milling method have been studied. The sand samples were processed using an Iron Sand Separator (ISS) and NdFeB magnet in order to separate between iron and non iron oxides particles prior to ball milling process. The result is called an NdFeB product, then the NdFeB product was milled using ball milling for 3 stages. The first, second and third stage milling were done for 3, 15 and 102 hours. Each of ball milling product was processed using NdFeB magnet in order to separate between iron and non iron oxides particles. The latter product is called the BM 3. The BM 3 product was divided into 5 parts in equal weight and then doped using Nickel (Ni) nanoperticles with a concentration of (0; 5; 10; 15 and 20) wt% for 20 hours using ball milling and the products are called BM4A, BM4B, BM4C, respectively. Three selected samples namely BM4A, BM4B and BM4C were characterized using a Scanning Electron Microscope (SEM). Magnetic Susceptibility was calculated based on the values of magnetic induction (BO) and total magnetic induction (BT) of the solenoid. The results showed that susceptibility increases with increasing concentration of Nickel doping and thesevalue is in the range of iron oxide nanoparticles. The results of SEM analysis showed that the particle size varied from 740 nm, 880 nm and 1220 nm with an increase in Nickel concentration of 0 wt.%, 5 wt.% and 10 wt.%, respectively.en_US
