Research on magnetic properties based on hysteresis loop parameters and
morphology of iron oxide nanoparticles prepared from Ulakan – Pariaman sand
beach using ball milling method has been carried out. The iron and non iron oxide
particles of sand sample was separated using an Iron Sand Separator (ISS) then the
product was separated again between iron and other iron oxides using a Neodymium
Iron Boron (NdFeB) magnet, the result is called a NdFeB product. The NdFeB
product was milled through stage one for 3 hours with a ball milling diameter of 1,5
cm as many as 18 balls, the result is called BM 1 product. The BM 1 product was
separated from iron and other oxides using NdFeB magnet. The second stage ball
milling was done for 15 hours with the same milling balls, the result is called BM 2
product. BM 2 product was separated again from iron and other oxides using
NdFeB magnet, then milled again for 102 hours with a combined diameter of 1.5
cm milling balls as many as 18 balls and 0,5 cm as many as 50 balls, the result is
called BM 3 product. BM 3 product was divided into 5 parts, then each part was
doped with Cu (copper) as a function of weight concentration of using ball milling
for 20 hours with the same milling ball parameters diameters, the results are called
composite nanoparticles (Fe3O4)100-xCux where x= 0; 5; 10; 15; and 20 (weight %).
Magnetic susceptibility was calculated based on the value of the magnetic induction
of the solenoid (B0) and the total magnetic induction of the solenoid (BT) using the
Pasco PS-2162 magnetic probe as a function of the currents of 200 mA; 400 mA;
600 mA; 800 mA; and 1000 mA. The solenoid parameters used are 2500 turns, 10
cm long, and 3 cm in diameter. Magnetic properties were studied based on
hysteresis loops of magnetic nanoparticles using Vibrating Sample Magnetometer
(VSM). The results showed that the saturation magnetization (Ms) and remanent
magnetization (Mr) varied depending on the copper concentration (weight %), while
the magnetic coercivity (Hc), the squareness of the loop (Mr/Ms), and loop area (A)
increased along with an increased copper concentration (weight %). The size and
shape of the iron oxide nanoparticles were determined by Scanning Electron
Microscope (SEM). The results of the SEM analysis showed that the fine flakes
began to decrease and seemed to start to coalesce (clump) or agglomerate in the
sample as the copper concentration (weight %) used was increased.
