Abstract

Fe-Ni alloy nanopartieles were synthesized by thermal decomposition of Ni(COOH)₂and Fe(CO)₃ with 1-octadeeene as the solvent and oleic acid(OA) and oleylamine(OLA) as surfactants. The produced Fe-Ni alloy nanopartieles were characterized by X-ray diffraction(XRD), transmission electron microscope(TEM) and vibrating sample magnetometer (VSM). The results showed that a shape controlled fee phase Fe-Ni alloy nanopartieles of triangular shape was formed when the molar ratio of OA, OLA and Ni(HCOO)₂ was 4:2:1 at 200 °C fo 20 min. Magnetic measurements revealed the alloy nanopartieles of triangular shape exhibit superparamagnetic behavior with a saturation magnetization of 15.5 emu·g^-1 at 300 K; a saturation magnetization of 17.5 emu·g^-1 and a coer-civity of 158 Oe at 4.2 K.
