BaFe12-2xNixCoxO19 (x = 0, 0.1, 0.2 % mol) was synthesized using chemical coprecipitation method. BaCl2, FeCl3, NiCl2 and COCl2 powder were mixed and precipitated with 1M NaOH solution using as precipitant. Nickel and Cobalt dopan influence on the structure, morphology and magnetic properties were characterized using XRD, SEM and VSM. The results of XRD analysis showed that all samples have a dominant phase BaFe12O19 hexagonal while the calcined samples showed no peak. Shifting the corner in terms of the field (114) indicates 2θ angle shifted towards larger. VSM data indicates that the sample without calcination showed paramagnetic properties and low coercivity figures showed. Calcined sample has a coercivity value tends to increase with increasing calcination temperature used.
