Structural Properties of Cerium Substituted Yttrium Iron Garnet

Abstract

The cerium-substituted yttrium-iron garnet (Ce-YIG) in CexY3–xFe5O12 is considered as a promising material for applications in high frequency wireless communication technology. In this work, we reported the structural properties of Ce-YIG. This material was produced via conventional solid state reaction (CSSR) with various molar ratio of cerium (x = 0.0, 0.1, 0.5, 1.0, and 1.5, respectively). A heat treatment was at a temperature of 1420 °C for 6 h after pre-fired at 1100 °C for 6 h. Multiple phases were presented in Ce-YIG ceramics. It was found, at x=1.5, the substitution of Ce into YIG has reached the solid solution limit. It was seen that, the peaks were shifted to the lower angle and proportional to the amount of Ce added. Thus, it can be concluded that, the substitution of Ce into YIG was successfully at x=0.1,0.5, and 1.0 respectively before reaching the solid solution limit at x=1.5.
