Influence of YIP Phase on Magnetic Properties of YIG Nanoparticles Prepared by Sol-Gel Method

Yttrium iron garnet and yttrium iron perovskite (yttrium orthoferrite) nanopowders were synthesized via citrate and glycol modifications of sol-gel technique. Phase composition and crystal structure parameters of these nanopowders were estimated from X-Ray diffraction patterns. Magnetization loops, ferromagnetic resonance and temperature dependence of magnetization measurements were performed to characterize magnetic behavior of investigated samples. Accordingly to results of these experiments influence of yttrium orthoferrite phase and synthesis method on magnetic properties of yttrium iron garnet nanopowders was analyzed.
