摘要：
We report the growth of Ce-substituted yttrium iron garnet (CeYIG) thin films deposited by pulsed laser deposition on quartz substrates. CeYIG exhibits a large Faraday rotation in the near-IR region. Upon investigating the phase composition and the magnetic and magneto-optical properties of the films, we present optimal process conditions for growing CeYIG thin films on quartz substrates. A saturation magnetization (Ms) as high as 159 emu/cm(3) was achieved by depositing a Ce-0.25 Y Fe-1.75(5) O (12) thin film at a substrate temperature of 650(ay)C and a 2-Hz laser pulse rate. Under the same depositing conditions, CeYIG thin films annealed at 800(ay)C for 40 min provided the largest Faraday rotation (FR) angle of -6000(ay)/cm by applying an out-of-plane magnetic field. Hence, CeYIG thin film materials show promise for magneto-optical and microwave communication applications.
