Title: Exceptionally high magnetization of stoichiometric Y 3Fe 5O 12 epitaxial films grown on Gd 3Ga 5O 12

The saturation magnetization of Y 3Fe 5O 12 (YIG) epitaxial films 4 to 250 nm in thickness has been determined by complementary measurements including the angular and frequency dependencies of the ferromagnetic resonance fields as well as magnetometry measurements. The YIG films exhibit state-of-the-art crystalline quality, proper stoichiometry, and pure Fe 3+ valence state. The values of YIG magnetization obtained from all the techniques significantly exceed previously reported values for single crystal YIG and the theoretical maximum. This enhancement of magnetization, not attributable to off-stoichiometry or other defects in YIG, thus opens opportunities for tuning magnetic properties in epitaxial films of magnetic insulators.
