Abstract

Yttrium iron garnet (YIG) is a synthetic Ferrimagnetic material. YIG is cubic in structure; having space group Ia3d. In YIG, out of 5 Fe3+ ions, 3 Fe ions occupy tetrahedral site and 2 Fe ions occupy octahedral site. Difference in the spin orientation of the Fe3+ ions present in tetrahedral and octahedral sites results in the origin of the magnetic properties of YIG. Yttrium iron garnet with the empirical formula Y3 Fe5 O12 has been synthesized by regular ceramic route and sintering at 1200?C for 30 minutes using microwave furnace. The structural and morphological characterization of the synthesized YIG are performed by X-ray diffractometer (XRD), and scanning electron microscopy (SEM). X-ray diffraction pattern revealed pure YIG phase as reported by Musa et al [1]. The crystallite size from the Scherrer equation is found to be 2.82Å. A saturation magnetization of 16.88emu/g is achieved by VSM.
