Temperature study of magnetic resonance spectra of co-modified (Co,N)-TiO2 nanocomposites
Abstract
<jats:title>Abstract</jats:title><jats:p>The (nCo,N)-TiO<jats:sub>2</jats:sub> (n = 1, 5 and 10 wt.% of Co) nanocomposites were investigated by magnetic resonance spectroscopy in 4 K to 290 K range. Analyses of ferromagnetic/electron paramagnetic resonance (FMR/EPR) spectra in terms of four Callen lineshape components revealed the existence of two types of magnetic centers, one derived from metallic cobalt nanoparticles in superparamagnetic (SPM) phase and the other from cobalt clusters in the TiO<jats:sub>2</jats:sub> lattice. Additionally, at low temperature the EPR spectrum arising from Ti<jats:sup>3</jats:sup>+ ions was also registered. Both relaxations of the Landau-Lifshitz type and the Bloch-Bloembergen type played an important role at high temperature in determining the linewidths and the latter relaxation was prevailing at low temperature. Analysis of the integrated intensity showed that the SPM signal is due to small size FM cobalt nanoparticles while the paramagnetic signal from Co clusters originates from those nanoparticles in which the concentration of magnetic polarons is below the percolation threshold.</jats:p>
