| Abstract: | The structural and bulk magnetic properties of Fe3+ substituted yttrium iron garnet with general formulaY3-xFe5+xO12 (x = 0.0, 0.05, 0.15,0.30 and 0.50) have been investigated by means of X-ray diffraction, EDAX, high field magnetization and low field a.c. susceptibility measurements. It is found that substituted Fe3+ ions occupy c-sites and increase in lattice constant for x> 0.30 is due to presence of Fe2+ ions, determined through EDAX, on a-sites. Variation of magneton number with x can be explained satisfactorily assuming the collinear spin ordering model and Neel temperature values deduced experimentally from a.c. suscepti bility measurements are in good agreement to those calculated theoretically. |
