Analisis Sifat Kemagnetan Nanomaterial Magnetik ZnFe2O4 Berbahan Dasar Pasir Besi Dengan Metode Kopresipitasi
Abstract
Iron sand is a natural resource rich in iron oxide compounds such as Fe?O?, ?-Fe?O?, and ?-Fe?O?, which have the potential to be developed into functional materials, particularly magnetic nanoparticles. This study aims to analyze the magnetic properties of ZnFe?O? nanomaterials synthesized from iron sand using the coprecipitation method. The synthesis was carried out by dissolving iron sand in HCl, mixing with a ZnCl? solution and titrating with NH?OH until a dark brown precipitate was formed. The precipitate was heated at 200?°C for 2 hours. Characterization was conducted using X-Ray Diffraction (XRD), Scanning Electron Microscopy (SEM), and Vibrating Sample Magnetometry (VSM). XRD results confirmed the presence of ZnFe?O? phase by JCPDS No. 22-1012, with a crystallite size of 24.9 nm and a lattice parameter of 8.28 Å. SEM images revealed non-uniform particle morphology and agglomeration. VSM results showed a remanent magnetization (Mr) of 0.0016 emu, coercivity (Hc) of 314 Oe, and saturation magnetization (Ms) of 1.540 emu. Based on these results, the material exhibits soft ferromagnetic behavior consistent with the spinel structure of ZnFe?O?.
