Transmission electron micrographs and X-ray powder diffraction patterns show that the average particle sizes are in the range of 9-50 nm. From the electron spin resonance (ESR) patterns of 9 nm manganic oxide particle, we can observe hyperfine structure (Six absorption peaks of ESR) of Mn2+ ion adding the Mn3+ ion signal. 关键词: Manganese compounds;Nanostructured materials;Electron spin resonance spectroscopy;Transmission electron microscopy;X ray powder diffraction;Particle size analysis;Crystal structure;Precipitation (chemical);Manganic oxide;Chemical liquid homogeneous precipitation (CHLP) method;Hyperfine structures
