Abstract
The Mossbauer Effect study of polycrystalline Gadolinium Iron Garnet has been undertaken between 714K and 4.2K. The temperature dependence of the sublattice magnetization has been determined at the two iron sites and the direction of the hyperfine fields at each site is [111] over the entire temperature range. The saturation fields at the octahedral and tetrahedral sites are respectively 547 kOe and 477 kOe. The ferrimagnetic Neel temperature has been found to be 562.5K and above this temperature, the quadrupole splitting at the octahedral and tetrahedral sites are −0.43 mms−1 and ¦0.89¦mms−1 respectively.
