Pengaruh Doping Mangan Terhadap Sifat Magnetik Dan Morfologi Dari Nanopartikel Magnetik

---

Magnetic and morphological properties of magnetic nanoparticles of natural sand
from Sungai Suci Beach in Pondok Kelapa District, Bengkulu Province have been
determined. The natural sand that has been extracted was processed using an Iron
Sand Separator (ISS) then the product was milled using ball milling which separated
between magnetic and non-magnetic minerals using magnet Neodymium Iron Boron
(NdFeB). The NdFeB product was milled using ball milling for 120 hours with a
milling ball diameter of 1.5 cm the result is called BM I product. BM I products were
doped using Manganese with concentrations of 0wt.%, 5wt.%, 10wt.%, 15wt.% and,
20wt.%. The doping process was carried out using ball milling for 20 hours with a
milling ball diameter of 1.5 cm, the result is called BM II Product. The solenoid
magnetic induction (B0) and the total solenoid magnetic induction (BT) were
measured using the Pasco Magnetic Probe PS-216. The magnetic susceptibility of the
sample was calculated based on the values of B0 and BT. The magnetic properties of
BM II products were determined using a Vibrating Sample Magnetometer (VSM)
based on the hysteresis loop. The results showed that the magnetization value
decreased with the increase of manganese concentration, the coercivity (Hc) and
loop squareness values increased with the increase of manganese, the remanent
magnetization value varied with the maximum value at 10wt.% manganese
concentration. Scanning Electron Microscope (SEM) was used to determine the
morphology of the samples. Along with the addition of manganese concentration,
clumping or agglomeration occurred in the BM II Mn10 wt.% and BM II Mn 20 wt.%
samples and the particle sizes became smaller and finer.
