【Abstract】 Hexagonal ferrite samples of La xBa 1-x Fe 12 O 19 (x≤0 2) have been prepared by a sol gel method. The composition ratios of the samples were confirmed by atomic absorption spectrometry and chemical analysis. The results of XRD, DTA, TGA and SEM showed that the samples have the same crystal structure as barium ferrite, with grain sizes being less than 1 μm.更多还原
