| Abstract: | In this paper, SrFe 12 O 19 is prepared by sol gel technique. Their absorption properties have been studied,it is found that when the coat thickness is 1.00mm,the absorption peak is highest and the absorption peak frequency is 10.0GHz.The absorption properties of different annealing temperatures have been compared with when the coat thickness is 1.00mm. |
