Abstract
YIG particles were obtained by Pechini method with a thermal annealing between 800 and 1200 °C. The formation of the cubic YIG phase was corroborated by means of X-ray diffraction (XRD), where YIG particles have crystallite size range between 107 and 303 nm. Magnetization dynamics were studied by means of magnetization hysteresis cycles, ferromagnetic resonance, and micromagnetic simulations. Different magnetic processes were determined as particle size function, and the magnetization dynamics can be explained by different contributions, such as single domain state, magnetic vortex state, and superparamagnetic behavior, besides considering their interactions.
