Sol-gel Auto-combustion Synthesis and microwave electromagnetic property of Perovskite-type LaMnO3 nanocrystalline

摘要

The perovskite-type nanocrystal LaMnO3 was prepared using a sol-gel auto-combustion method with citric acid as the chelating agent. The analytical methods of XRD, TEM and wave-guide were used to characterize the products. It was shown that the nanocrystalline had dielectric loss in the microwave frequency range of measurement.
