Abstract :
Epitaxial Y3Fe5O12 films are grown on (111) gadolinium gallium garnet substrates using the pulsed laser deposition technique. The results demonstrate that epitaxial YIG films could be prepared under a wide range of deposition conditions, but narrow linewidth (ΔH≅1 Oe) films are produced only at low oxygen partial pressures and relatively high substrate temperatures. The films exhibit a uniaxial magnetic anisotropy parameter which changes sign from negative to positive with increasing oxygen partial pressure
