摘要：
The investigation of optical and electron spin resonance (ESR) spectroscopic properties are carried out. Six characteristic absorption bands related to distinctive conglomerates of FemOn formed via sol-gel synthesis process on SiO2 porous matrix are observed in optical spectra. ESR spectra investigation makes it possible to reveal small characteristic signal associated with magnetostatic interactions between conglomerates of FemOn nanoparticles.
