报道了Ag3PO4/ srfe12o19异质结构的合成，其中Ag3PO4亚微立方生长在srfe12o19纳米片表面。研究了该异质结构在2-18 GHz波段的微波吸收性能。由于介质损耗与磁损耗之间存在互补现象，介质损耗因子与磁损耗因子之和几乎保持不变，表明微波的损耗能力没有变化。该异质结构在2.3 mm处的有效带宽为5.2 GHz，覆盖12.4-17.4和17.8-18.0 GHz。理论模拟表明，界面极化导致了优异的微波吸收性能。
The synthesis of Ag3PO4/SrFe12O19heterostructure is reported, in which Ag3PO4sub-microcubic grows on the surface of SrFe12O19nanoflake. The microwave absorption performances of the heterostructure are investigated in 2–18 GHz. Due to the complementary phenomenon between the dielectric loss and magnetic loss, the sum values of dielectric loss factor and magnetic loss factor almost keep a constant, indicating no change of loss ability on microwave. The heterostructure exhibits the broad effective bandwidth of 5.2 GHz at 2.3 mm, covering 12.4–17.4 and 17.8–18.0 GHz. The theoretical simulations reveal the interfacial polarization leads to the outstanding microwave absorbing performances.
