Abstract

The change in the Curie temperature of single crystalline garnet Y₃Fe₅O₁₂ (YIG) sample due to lattice damage induced by ion implantation has been investigated in ⁵⁷Fe emission Mössbauer Spectroscopy (eMS) following implantation of ⁵⁷Mn (T_½ = 1.5 min). The Mössbauer spectra analysis reveal high spin Fe³⁺ ions substituted on both the octahedral and the tetrahedral sites. Measurements in the temperature range 298 K–798 K show that average values of the magnetic hyperfine field are decreased by the implantation-induced damage on the local lattice structure of the YIG. The Curie temperature, however, is determined to be 651 ± 5 K, considerably higher than the value of bulk YIG (559 K). This is most likely due to lattice damage-induced changes on the spin configurations of YIG through a Fe_A-O-Fe_D distortion scheme.
