Sublattice spin reversal and field induced $Fe^{3+}$ spin-canting across the magnetic compensation temperature in $Y_{1.5}Gd_{1.5}Fe_{5}O_{12}$ rare-earth iron garnet
Abstract:In the present work Fe 3+ & Gd 3+ sublattice spin reversal and Fe 3+ spin-canting across the magnetic compensation temperature (TComp) are demonstrated in polycrystalline Y1.5Gd1.5Fe5O12 (YGdIG) with in-field 57 F e Mössbauer spectroscopy and hard x-ray magnetic circular dichroism (XMCD) measurements. From in-field 57 F e Mössbauer measurements, estimation and analysis of effective internal hyperfine field (H eff ), relative intensity of absorption lines in a sextet elucidated unambiguously the signatures of F… Show more
