Superexchange and iron valence control by off-stoichiometry in yttrium iron garnet thin films grown by pulsed laser deposition
Controlled off-stoichiometric single phase polycrystalline yttrium iron garnet (YIG) thin films have been grown by pulsed laser deposition, adjusting the oxygen partial pressure P O 2 between 5 and 400 mTorr. Atomic stoichiometry by RBS shows an oxygen deficiency for P O 2 < P stoich and iron and...
