Abstract

In this study, YTTRIUM IRON GARNET NANOPARTICLES with the chemical formula Y3Fe5O12 under both atmospheric and nitrogen atmosphere were prepared by MICROEMULSION method. Structural and magnetic properties were studied by XRD, Far- FTIR, TEM, VSM, for termal was annealing investigation at 700oC-1100oC. Phase formation were studied by X-Ray diffraction (XRD). X-Ray diffraction analysis (XRD) show the samples at the temperature 800oC and 900oC are single phase. The average crystallite sizes under two atmospheres (nitrogen and atmosphere) were estimated to be in the range of 11 to 29 nm. Far- infrared spectrometry (Far-FTIR) show that main bond of u1 in the range of 550-650 cm-1 is tetrahedron and u2 bond in a range 300-400 cm-1 is related to the octahedral sites. Image of transmission electron microscopy (TEM) shows that the particle size distribution is uniform. YTTRIUM IRON GARNET prepare magnetic we also studied by use of a vibrating sample magnetometer (VSM). In this analysis at first, saturation magnetization of samples increases to temperature 900oC and then decreased. These chenges were attributed to the increase of phase side effects and lack of oxygen at higher temperatures.
