Název v původním jazyce

Evaluation of Fe-nitrides, -borides and -carbides for enhanced magnetic fluid hyperthermia with experimental study of α''-Fe16N2 and ε-Fe3N nanoparticles

Popis výsledku v původním jazyce

Alternative materials systems that have the potential to deliver enhanced heating power in magnetic fluid hyperthermia are investigated. The focus lies on systems with high magnetization phases, namely iron-nitrogen, iron-boron and iron-carbon compounds, and their performance in comparison to the conventionally used iron oxides. The heating power as a function of the AC magnetic field frequency is calculated and the particle size with the maximum specific loss power is identified. It is found that lower anisotropy results in larger optimum particle size and more tolerance for polydispersity. The effect of nanoparticle saturation magnetization and anisotropy is simulated, and a material with high magnetization but low anisotropy provides the best combination. These findings are juxtaposed with experimental results of a comparative study of alpha''-Fe16N2, epsilon-Fe3N, and iron oxides nanoparticles.
