Abstract EN
Al substituted barium ferrite particles BaFe12-xAlxO19 with 0 ≤ x ≤ 0.8 have been prepared by ball milling method.
X-ray diffraction (XRD) has shown that the average crystallite size for all samples under investigation is in the range 66 – 76 nm.
Scanning electron microscopy (SEM) imaging indicates that the particle size is in the range 0.2 – 1.0 μm, which demonstrates that the particles are polycrystalline.
It was found that Al substitution does not significantly change the particle size of BaFe12-xAlxO19.
The magnetic properties have been investigated using a vibrating sample magnetometer, and the anisotropy field is estimated.
It was found that the coercivity of the samples increases from4.2 kOe to 6.0 kOe with increasing Al concentration from x = 0.0 to 0.8 due to the increase in the anisotropy field.
Interparticle interactions determined from the remnant magnetization data are found to be consistent with a reversal mechanism (demagnetizing like effect) for all samples examined.
