Title: Morphology and magnetic properties of Fe3O4 - alginic acid nanocomposites |
Source: Materiali in Technologije |
Year : 2014 |
The morphology, structure and magnetic properties of the nanocomposites of magnetite (Fe3O4) nanoparticles and alginic acid (AA) are studied. Magnetite Fe3O4 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 Fe3O4-AA nanocomposites at low temperatures. |
