Processing of gadolinium–iron garnet under non …

Abstract. We have investigated the mechanosynthesis of gadolinium iron garnet (GdIG) by high-energy ball-milling of 3.(Gd 2 O 3) + 10.(α-Fe) followed by thermal annealing conducted at moderate temperatures (1100 °C).The samples were characterized by X-ray diffraction and Moss spectroscopy in order to determine the influence of the milling time on the final products.
