The purpose of this study is to determine the magnetic properties and morphology
of iron oxide nanoparticles of natural sand collected form Logas Village, Kuantan
Singingi Regency, which was doped with nickel. Natural sand samples were
separated between magnetic and non-magnetic particles using a strong magnet
Neodymium Iron Boron (NdFeB), the result of the separation is called the NdFeB
product. This NdFeB product was milled using the first stage of Ball Milling with
18 balls that have 1.5 cm as its diameter for 3 hours, the product is called BM 1
product. BM 1 product was separated from iron and other oxides using NdFeB
magnets. The second stage of ball milling with another 18 balls that have 1.5 cm
as its diameter and it lasts for 15 hours, the product also known as BM II. The
BM 2 product is separated from iron and other oxides using an NdFeB magnet,
then ball milling process starts again for 102 hours using 18 balls with a size of
1.5 cm and 0.5 cm. BM 3 was divided into 5 equal parts and each was doped with
nickel (Ni) with a weight concentration of 0 wt%; 5 wt%; 10 wt%; 15 wt%; and
20 wt% for 20 hours using ball milling. Magnetic susceptibility was calculated
based on the magnetic induction of the solenoid (B0) and the total magnetic
induction of the solenoid (BT) using Pasco PS-2162 magnetic probe as a function
of the electric currents of 100 mA, 200 mA, 400 mA, 600 mA, and 800 mA. The
solenoid parameters used are 2500 turns, 10 cm long, and 3 cm in diameter. BM 3
products with weight concentrations of 0 wt%; 5 wt%; and 10 wt% were selected
for being characterized using Vibrating Sample Magnetometer (VSM) to
determine the magnetic properties of the product through their Loop hysteresis.
The results showed that the saturation magnetization (Ms), remanent
magnetization (Mr) and loop area (A) increased with the addition of nickel
concentration, while the coercivity (Hc) and loop squareness (S) varied depending
on the addition of nickel concentration. The results of the Scanning Electron
Microscope (SEM) test showed that the particle sizes became smaller that is 0.088
m, 0.067 m, and 0.066 m as the nickel concentration increased.
Keywords : Natural sand, Ball milling, Magnetic susceptibility, Nickel doped (Ni),
