چکیده
Nanodisperse powder of zinc-substituted magnetite has been developed. Functional characteristics (biocompatibility, dispersion, magnetic state) allow to recommend it for approbation in medical and biologic technologies. The character of the temperature dependences of magnetization investigated in the magnetic fields lower than the anisotropy field indicates that transfer from the magnetically stable state into the superparamagnetic state was realized for particles of 3-13 nm in the temperature range of 4.2-150 K. It reflects specificity of small particles magnetism.

متن کاملSize-dependant heating rates of iron oxide nanoparticles for magnetic fluid hyperthermia.
Using the thermal decomposition of organometallics method we have synthesized high-quality, iron oxide nanoparticles of tailorable size up to ~15nm and transferred them to a water phase by coating with a biocompatible polymer. The magnetic behavior of these particles was measured and fit to a log-normal distribution using the Chantrell method and their polydispersity was confirmed to be very na...
