Research Progress on Gallium Garnet Series Single Crystal with Large Lattice Constant for Magneto-Optical Substrates
摘要
Abstract
;With the rapid advancement of optical communication technology and integrated electronic devices,magneto-optical thin films,particularly rare earth iron garnet(RIG),have emerged as the most promising materials for near-infrared communication windows in recent years.In order to minimize the impact on the related properties of magneto-optical thin films during the preparation process,it's important to select the substrate materials.Silicon and garnet oxides are commonly used as substrates for the preparation of RIG magneto-optical thin films.The lattice constant of RIG magneto-optical thin films is generally around 12.4 A,and gallium-containing garnet oxide single crystal substrates have a similar lattice constant,which shows large lattice constant characteristics,making them one of the suitable substrate materials.However,the raw material gallium oxide is volatile at high temperature,the preparation of gallium-containing garnet single crystal has been a hot topic.The further study of gallium garnet series substrate single crystals is expected to promote the development of a new magneto-optical devices.In this paper,we reviewed the research of gallium garnet series single crystal,summarized the work of our team in the growth,structure and key parameters of these crystals,and outlooked the trend of research and development.关键词
