| Opis: | A chemical and a physical method have been applied for the preparation of chromium-nickel alloy nanoparticles. These particles were designed to be used for controlled magnetic hyperthermia applications. Microemulsions with $Ni^{2+}$ and $Cr^{3+}$ and/or $NaBH_4$ as precursors were prepared using the isooctane/CTAB, n-butanol/$H_2O$ system. The samples of $Cr_xNi_{1-x}$ nanoparticles with the desired composition were obtained after the reduction of their salts with $NaBH_4$ and afterwards heat treated in a TGA in a $N_2$ atmosphere at various temperatures. The $Cr_xNi_{1-x}$ materials were also prepared by mechanical milling. Utilizing a ball-to-powder mass ratio of 20 : 1 and selecting the proper alloy compositions we were able to obtain nanocrystalline $Cr_xNi_{1-x}$ particles. Thermal demagnetization in the vicinity of the Curie temperature of the nanoparticles was studied using a modified TGA-SDTA method. The alloyʼs phase composition, size and morphology were determined with XRD measurements and TEManalyses. |
