"Spruce sawdust (lignocellulose material) was magnetically modified after a contact with the water-based magnetic fluid containing maghemite nanoparticles. The magnetic sawdust was investigated by means of ESR spectroscopy and conventional magnetic methods. The experimental results clearly show that the magnetic behavior of the sample is determined by two distinct magnetic contributions. One of them is connected to the presence of isolated single domain maghemite nanoparticles of 11 nm in diameter, which exhibit a superparamagnetic behavior at T > 280 K. The second one is related to the presence of agglomerates of particles coupled by magnetic dipolar interactions."@en . . . "sawdust; magnetic"@en . . . . . . "6490;6496" . .
