摘要: Abstract (RE,Y) 3 (Fe,Ga) 5 O 12 garnets, where RE=Eu or Gd, have been developed for use as magnetic bubble domain materials. Magnetic and crystallographic studies were used to find suitable compositions epitaxial thin films on nonmagnetic garnet substrate crystals. Properties of grown by liquid phase epitaxy Czochralski Gd-Ga (111) substrates are discussed. Uniaxial anisotropy in the can be interpreted being result a lattice mismatch stress mechanism. The Gd-Y with uniaxial tension while Eu-Y compression shown spacing differences between their substrates. Uncracked, high stability very compressive stresses grown. Annealing experiments reveal significant changes which correlate large film spacing. Thus, it is possible obtain garnets containing only one kind rare earth ion together such yttrium. These support domains wall velocities at typical device drive fields.
