Abstract
Gadolinium iron garnet (GdIG) Gd3Fe5O12 was prepared using the autocombustion method with glycine as fuel. The GdIG samples revealed single phase garnet with cubic symmetry. The effect of (glycine/nitrate) ratio on the structural and magnetic properties of the investigated garnet is reported. The results of the study indicated that the lattice parameter decreased with a remarkable improvement of the densification with increasing (glycine/ nitrate) ratio.
