Sublattice spin reversal and field induced Fespin-canting across the magnetic compensation temperature in YGdFeOrare-earth iron garnet.

In the present work Fesublattice spin reversal and Fespin-canting across the magnetic compensation temperature (TComp) are demonstrated in polycrystalline YGdFeO(YGdIG) by means of in-field57FeMössbauer spectroscopy measurements. Corroborating in-field57FeMössbauer measurements, both Fe& Gdsublattice spin reversal has also been manifested in hard x-ray magnetic circular dichroism (XMCD) measurements. From in-fieldMössbauer measurements, estimation and analysis of effective internal hyperfine field (Heff), relative intensity of absorption lines in a sextet elucidated unambiguously the signatures of Fespin reversal and field induced spin-canting of Fesublattices across TComp.
