Abstract

Ni1-xZnxFe2O4 nanoparticles (a few nm in diameter) were produced by low-temperature solid-state reaction (LTSSR) method. Magnetic and structural properties of the products were investigated by scanning tunneling microscopy (STM), Xray diffraction (XRD), alternating gradient-force magnetometery (AGFM) and transmission electron microscopy (TEM). The Curie temperature was also determined for several samples. Energy dispersive X-ray (EDX), X ray fluorescence (XRF) and atomic absorption spectroscopy (AAS) analysis were taken from some samples in order to recheck the elemental results. The effect of x parameter on saturation magnetization was studied. It was found that the maximum saturation magnetization occurred at x=0.5 (Ni0.5Zn0.5Fe2O4)..
