文摘
- •
Lithium–Zinc ferrite hollow microspheres (LiZn FHMs) doped with La and Mg were synthesized.
- •
Self-quenching technology was first used to prepare LiZn FHMs doped with La and Mg.
- •
The phases remain unchangeable after Mg doping, while LaFeO3 appears after La doping.
- •
After La doping, the minimum reflectivity of LiZn FHMs is −30.2 dB at 6.2 GHz.
- •
The microwave absorption properties are improved after La doping, and reduced after Mg doping.
