Yttrium iron garnet (YIG: Y 3 Fe 5 O 12 ) ferrite powders were obtained by the Pechini method from metal nitrates, citric acid and ethylene glycol followed by thermal annealing at T an = 900°C, 1000°C, 1100°C and 1200°C. X-ray diffraction (XRD) and Raman spectroscopy were used to study the structural and vibrational properties of YIG powders. Raman spectra of powders showed the same set of bands as the bulk YIG, but they are broadened due to spatial confinement of phonons. Magnetic properties were measured by vibrant sample magnetometer (VSM), founding that magnetic properties are strongly dependent on T ann ; in particular the magnetization increases and reaches the bulk value of 27.7 emu/g at T = 1000°C.
