Morphology and magnetic properties of Fe<inf>3</inf>O<inf>4</inf>-alginic acid nanocomposites
Abstract
<p>The morphology, structure and magnetic properties of the nanocomposites of magnetite (Fe<sub>3</sub>O<sub>4</sub>) nanoparticles and alginic acid (AA) are studied. Magnetite Fe<sub>3</sub>O<sub>4</sub> nanoparticles and the nanoparticles capped with alginic acid exhibit very distinct properties. The chemical bonding between alginic acid and the surface of magnetite nanoparticles results in the recovery of surface magnetization. On the other hand, it also leads to the enhanced surface spin disorder and unconventional behavior of the magnetization observed in Fe<sub>3</sub>O<sub>4</sub>-AA nanocomposites at low temperatures.</p>
