STRUCTURAL AND MAGNETIC PROPERTIES OF CERIUM-DOPED YTTRIUM-IRON GARNET THIN FILMS PREPARED ON DIFFERENT SUBSTRATES USING THE SOL-GEL PROCESS

WOS: 000319783400008The cerium-substituted yttrium-iron garnet (Ce-YIG) CexY3-xFe5O12 is considered as a promising material for applications in high-performance magnetic and magneto-optic devices. In this work cerium-substituted yttrium-iron garnet films were produced on fused silica and Si(100) substrates using the sol-gel technique from solutions with the yttrium/cerium molar ratio 2.8/0.2. A heat treatment was applied to those as-deposited garnet films at temperatures ranging from 800 degrees C to 1000 degrees C for 2 h in air. The as-deposited garnet films were characterized by X-ray diffraction (XRD) and scanning electron microscopy (SEM) to investigate their structural properties. A vibrating-sample magnetometer was used at room temperature to characterize the magnetic properties of the as-deposited garnet thin films.Scientific and Technological Research Council of Turkey (TUBITAK)Turkiye Bilimsel ve Teknolojik Arastirma Kurumu (TUBITAK) [106T651]This work was financially supported by the Scientific and Technological Research Council of Turkey (TUBITAK, project number 106T651)
