Abstract :
With different weight ratio of carbonyl iron powder and La1-xSrxMnO3 (x=1.3, 0.4, 0.5) powder have been prepared by physical method. The structure, morphology and microwave absorption properties have been investigated. The results show that the ratio of carbonyl iron powder to La1-xSrxMnO3 has great influence on reflection loss. The optimal absorption property can be obtained when the weight ratio of the carbonyl iron powder to La0.06Sr0.4MnO3 is 30:1, which is attributed to the balance of the electric-magnetic match.
