TL;DR: Ferromagnetic resonance (FMR) and ac conductivity measurements have been applied to study a polymer composite containing as filler a binary mixture of magnetite (Fe3O4) and cementite nanoparticles (30-50nm) dispersed in a diamagnetic carbon matrix, which was synthesized by the carburization of nanocrystalline iron.

TL;DR: In this paper, two magnetic nanocomposites were prepared from nanocrystalline zinc oxide doped with different concentrations of iron oxide (5 and 10 %) X-ray diffraction and scanning electron microscopy have shown the growth of ZnFe2O4 nanocrystites with size below 10nm within the ZnO matrix in a highly agglomerated structure Ferromagnetic resonance (FMR) measurements have shown line arising from the nanoparticles, temperature dependence of the FMR spectra parameters (amplitude, resonance field, linewidth,
