Abstract
YIG films, substituted with Bi, Ti, Ga and La, were grown on a (111) plane of Gd3Ga5O12 or (Gd, Ca)3(Ga, Mg, Zr)5O12 by a liquid phase epitaxial method. With the increase of the concentration of Bi atoms, which are substituted at 24c sites of YIG, the magnetic hyperfine fields at 16a and 24d Fe sites increased and the direction of magnetic moments changed from parallel to 45° to the (111) plane. With the increase of Ga concentration, the hyperfine fields at 16a and 24d Fe sites decreased. The hyperfine interaction and the substitution effect of YIG films are discussed.
