Abstract
High Energy Milling (HEM) followed by heat treatment was used to prepare M-type BaFe12O19/ZnO magnetic material in toluene media. High purity of BaFe12O19 and ZnO powder was milled for 12 h followed by drying for 4 h before being calcined at a temperature of 900C. The powder was then filtered by using T-200. An appropriate amount of BaFe12O19 and ZnO were then mixed in wet-milling for 15 mins and dried at 200C for 1 h. The magnetic properties were analysed using VSM, whereas the phase formation was derived from XRD-pattern (powder method) using X-ray CuKα 40kV-30mA with λ= 1.5418 Å. The phase occurrence was determined using MATCH-software program. It was obtained that BaFe12O19 lattice parameter: a = 5.8930 Å, c = 23.1940 Å. In order to get soft magnetic state, ZnO was added with a composition of: 0/100, 25/100, 50/100, 75/100, respectively. It was found that addition of 75% ZnO to BaFe12O19 converted hard magnet to soft magnet.
