Abstract EN
Precursor powders of BaMg2-xCoxFe16O27 with (x = 0.0, 1.0, and 2.0) were prepared using high-energy ball milling, and the effects of chemical composition and sintering temperature on the structural and magnetic properties were investigated using x-ray diffractometer (XRD), scanning electron microscopy (SEM), and vibrating sample magnetometry (VSM).
XRD patterns of the prepared samples indicated that crystallization of pure BaW hexaferrite phase was achieved at sintering temperature of 1300° C, while BaM and cubic spinel phase intermediate phases were obtained at lower sintering temperatures of 1100° C and 1200° C.
SEM images revealed improvement of the crystallization of the structural phases, and growth of the particle size with increasing the sintering temperature.
The magnetic data of the samples sintered at 1300° C revealed an increase of the saturation magnetization from 59.44 emu/g to 72.56 emu/g with increasing Co concentration (x) from 0.0 to 2.0.
The coercive field Hc decreased from 0.07 kOe at x = 0.0, to 0.03 kOe at x = 1.0, and then increases to 0.09 kOe at x = 2.0.
The thermomagnetic curves of the samples sintered at 1300° C confirmed the existence of the W-type phase, and revealed spin reorientation transitions above room temperature.
