The produced powders were calcined at 550 °C for 6 h and sintered at 1000 °C for 5 h to obtain the required phases. The powders were characterized by differential thermal analysis/thermogravimetric analysis (DTA/TG), X-ray diffractometry (XRD) and scanning electron microscopy (SEM), and vibrating-sample magnetometry (VSM). The XRD patterns indicated that the pure barium ferrite phase was not obtained. The presence of M-type BaFe11.6Mn0.4O19 was confirmed in the Ferrite B and Ferrite D patterns. In the Ferrite C pattern, there were the phases of BaFe12O19, Ba2Cu2Fe12O22 (X or Z-type) and Sr3Fe2O6.16. The Ba0.5Sr0.5Fe12 phase was easily observed in the Ferrite E pattern. The results showed that the dopant materials significantly change the particle shape of Ferrite A powders, but also lower the value of the coercivity. A higher saturation magnetization was observed for the Ferrite D powder"},{"@xml:lang":"sl","#text":"V tej raziskavi so prahovi ferita A (nedopiran barijev heksaferit), ferita B (MnCuNi, dopiran barijev heksaferit), ferita C (MnCuSr, dopiran barijev heksaferit), ferita D (MnCoNI, dopiran barijev heksaferit) in ferita E (MnCoSr, dopiran barijev heksaferit) pripravljeni po sol-gel metodi.

XRD-spektri so pokazali, da ni bila dosežena faza čisti barijev ferit. Prisotnost M-tipa BaFe11,6Mn0,4O19 je bila potrjena v feritih Bin D.
