제목 Synthesis of Bi-YIG Thin Film by Metal-Organic Decomposition Method
초록 In this study, Bi–substituted Y3Fe5O12 (Bi-YIG) thin films were prepared on gadolinim gallium garnet (GGG) substrate by using a metal-organic decomposition method (MOD). There are some advantages of this method: easier making, low cost and well control of composition. XRD-Analysis indicate that the crystallization temperature for Bi-YIG is 7000 C and an annealing time of 1hour. The pre-annealing is key to make single phase Bi-YIG and the temperature at 5500C is suitable to get single phase. And, we have also confirmed by Scan Electron Microscopy (SEM) that pre–post annealing by Rapid Thermal Annealing (RTA) does indeed reduce the grain size over an order of magnitude from films crystallized in a conventional furnace without pre-post annealing.
