Pengaruh Doping Nikel Terhadap Sifat Magnetik Nanopartikel Oksida Besi Pasir Pantai Ampalu Pariaman Dipreparasi Menggunakan Metode Ball Milling

---

Research on magnetic properties of iron oxide nanoparticles from Ampalu -Pariaman Beach sand was prepared using ball milling method and doped with nickel. Samples of Ampalu Beach sand were separated between iron oxides and non iron oxides particles using Iron Sand Separator (ISS). The next step was separation iron oxides and non iron oxides particles of the sample using strong magnet called Neodymium Iron Boron (NdFeB) which produces NdFeB product. Then NdFeB product was milled in 3 stages for 3 hours, 15 hours, and 102 hours for each stage. Each of the results of the milling process was separated using NdFeB magnet. The milling process took a total of 120 hours and the results called BM 3 product. BM 3 product was divided into 5 parts, each part was doped with nickel using ball milling method for 20 hours amount of 0; 5; 10; 15; and 20% nickel of the sample mass. The results of this process were tested for magnetic induction using the Probe Pasco PS-2162 with a current variation of 200 mA; 400 mA; 600 mA; 800 mA; and 1000 mA. The solenoid used in this test has 2500 turns, a length of 10 cm, and a diameter of 3 cm. The magnetic suseptibility of the sample is calculated based on the magnetic induction value of the coreless solenoid (B0) and the magnetic induction value of the sample (BT). The test results showed that the magnetic suseptibility value increases linearly with increasing nickel concentration. The next test was carried out using a Vibrating Sample Magnetometer (VSM). The test results showed that saturation magnetization (Ms) increases with increasing nickel concentration and magnetic coercivity (Hc), remanent magnetization (Mr), and loop squareness (Mr/Ms) had varying values depending on the amount of nickel concentration.
