“…Only a small amount of hexaferrite has been formed. Increasing the SPS temperature up to 700°C, the value of specific saturation magnetization at 1440 kA/m increases up to $0.32 T (67 emu/g), a value slightly higher than the reported for this type of hexaferrite [25], indicating its complete formation. The coercivity is about 286 kA/m (3.6 kOe), notably lower than the reported.…”

“…properties, corrosion resistance, chemical stability, and high performance-to-cost ratio. It has been recognized that they can be used as permanent magnets and high-density magnetic reordering media; they can also be used in telecommunication and as components in microwaves, higher frequencies, and magnetooptical devices [1][2][3][4]. The purity, size, and morphology of the powders affect its magnetic properties [5].…”

In this research, nano-sized powders of strontium hexaferrite were synthesized by sol-gel auto-combustion route using stoichiometric ratio of Fe/Sr. The effect cetyltrimethylammonium bromide (CTAB) addition on microstructure and magnetic properties of hexaferrite have been studied. The samples were characterized using X-ray diffraction (XRD), dynamic light scattering (DLS), vibration sample magnetometer (VSM), field emission scanning electron microscope (FESEM), and transmission electron microscope (TEM) techniques. The results revealed that CTAB addition causes a noticeable reduction in the amount of residual α-Fe 2 O 3 phase, since presence of CTAB in the sol facilitates the entrance of Sr 2+ ions into the reactions of hexaferrite formation. Also, the morphology of the particles was affected by CTAB addition. Irregular-shaped nanoparticles were synthesized without CTAB additions, while platelet-shaped nanoparticles were obtained by CTAB addition. The mechanism of strontium hexaferrite nanopowder formation has been explained. Magnetic measurements in the sample calcined at 800°C for 1 h represented that CTAB addition increased the coercivity force ( i H c ) from 4.9 to 5.2 kOe and maximum magnetization (M max ) from 48.4 to 60.4 emu/g, respectively.The online version of the original article can be found at http:// dx
