Comparison effects and electron spin resonance studies of alpha-Fe2O4 spinel type ferrite nanoparticles

WOS: 000340330800019PubMed ID: 24858357alpha-Fe2O4 spinel type ferrite nanoparticles have been synthesized by cetyltrimethylammonium bromide (CTAB) and ethylenediaminetetraacetic acid (EDTA) assisted hydrothermal route by using NaOH solution. Electron spin resonance (ESR/EPR) measurements of alpha-Fe2O4 nanoparticles have been performed by a conventional x-band spectrometer at room temperature. The comparison effect of nanoparticles prepared by using CTAB and EDTA in different alpha-doping on the structural and morphological properties have been investigated in detail. The effect of EDTA-assisted synthesis for alpha-Fe2O4 nanoparticles are refined, and thus the spectroscopic g-factor are detected by using ESR signals. These samples can be considered as great benefits for magnetic recording media, electromagnetic and drug delivery applications. (C) 2014 Elsevier B.V.
