Effect of Annealing for YIG Single Crystal Thick Films

ABSTRACT

When the PbO-based flux system is used in the Liquid Phase Epitaxy (LPE) method for Yttrium Iron Garnet (YIG) thick film, the effect of Pb ions incorporated into the grown crystal; increase the lattice parameter, changed the uniaxial magnetic anisotropy constant (Ku) or conductance of grown film. It exerts a bad influence on physical property such as increasing optical absorption of grown film. The content of the Pb ion in crystal was decreased by volatilization of Pb ion after annealing; therefore, the lattice parameter of film was reduced on an average 0.0115 ${AA}$ by the the Pb ion.

Key words: Yttrium Iron Garnet (YIG) thick film, LPE, Pb ion, Lattice parameter, Annealing
