Magnetic Heating by Cobalt Ferrite Nanoparticles

Original language description

In the quest for suitable materials for hyperthermia we explored the preparation and properties of nanoparticles of Co ferrite. The material was produced by coprecipitation from water solution of Co and Fe chlorides and afterwards annealed at 400, 600 and 800 °C. The resulting particles were characterized by XRD, TEM, Mössbauer spectroscopy, and dc and ac magnetometry. The heating experiments in ac magnetic fields of various amplitudes were performed with diluted systems of particles suspended in agarose gel and the results were interpreted on the basis of the ac magnetic losses measured at various temperatures. The increase of magnetic losses and consequently of the heating efficiency with increasing temperature is explained by the strong dependence of the constant of magnetocrystalline anisotropy of Co ferrite on temperature.

Kobaltnatoferitové nanočástice pro magnetický ohřev

Czech description

Mezi vhodnými materiály pro hypertermii byla zkoumána příprava a vlastnosti nanočástic Co feritu. Tepelné experimenty byly prováděny ve střídavých polích s různými amplitudami na zředěných systémech částic rozptýlených v agarosovém gelu. Výsledky byly interpretovány na základě měření magnetických ztrát v závislosti na teplotě.
