| Abstract: | We have studied the hyperfine interactions in GdIG in zero external magnetic field using57Fe Mössbauer spectroscopy. Measurements were made at temperatures between 80 K and 310 K, whereby the region around the compensation point at 286 K was emphasized. The easy axis of magnetization was determined to be 111] at all the chosen temperatures. No indications of spin canting were found. The hyperfine parameters vary smoothly with temperature. The temperature dependences of the magnetization of the sublattices are deduced from the magnetic hyperfine fields. |
