Abstract
- The present work reports the in-field 57Fe M ö ssbauer spectroscopy measurements on polycrystalline R3Fe5O12 (RIG, R=Y, Gd, Ho, Tm, & Yb) rare-earth iron garnets. The contrast between the effective hyperfine field (Heff) values of two Fe3+ sites (tetrahedral, d- and octahedral, a- sites) across magnetic compensation (TComp) facilitates to probe the Fe3+ sublattice spin reversal in RIG systems (R=Gd, Ho and Yb) exhibiting magnetic compensation. Further, the analysis of relative intensity of absorption lines in a sextet from the field dependent 57Fe M ö ssbauer spectroscopy measurements carried out in polycrystalline YbIG, below TComp, show the clear signatures of field induced perpendicular Fe3+ spin configuration when applied external field is 50 kOe.
