“…Ristic′ et al [13] found the same result when they carried out the YIG synthesis by co-precipitation and calcination. This phase was also observed when the sol-gel method was used instead [14,15]. In our previous work [16], we presented the YIG synthesis and made a complete structural characterization.…”

In recent years a great interest in the study of the association of magnetic with biological material for bioapplications has been observed in the literature. This work analyses the development of new magnetic biocomposite films from a magnetic ferrite and a biopolymer. Magnetic and dielectric properties of Y3Fe5O12 (YIG)/collagen composite films were studied as a function of the YIG concentration. This biocomposite was also characterized by Infrared Spectroscopy (IR), Thermal Analysis (DSC and TG) and scanning electron microspcopic (SEM) methods. The magnetization and dielectric measurements were performed at room temperature. The results demonstrated that ferrimagnetic garnet (YIG) and collagen (Col) can be used to obtain a homogeneous composite. All the composite films showed a ferromagnetic behavior and they were characterized as a soft magnet material. These results show that Col-YIG biocomposites are biological films with magnetic properties that can be employed as a versatile performance materials, due to their flexible dielectric and magnetic features. They could be used as electronic devices in biological applications

“…There are many different techniques or methods which can be employed to prepare YIG such as a sol-gel method [2][3][4], a solid state reaction technique [5], Low-Pressure Chemical Vapor Deposition (LPCVD) technique [6] and chemical co precipitation [7]. Among these techniques/methods, a sol-gel method is the most famous method.…”

“…Apart from being a cheap and simple method, the composition of resultant film of sol-gel method can be also controlled. Among the parameters that can influence resultant of the sol-gel method are chelating agents [2], solution concentration [2], pH of the solution [3], annealing temperature and aging time of the solution. Ftema et al, [3] have reported on the influence of pH value on the structure and magnetic properties of YIG thin films.…”

Abstract. Sol-gel yttrium iron garnet films were prepared at different solution aging time and annealing temperature. Microstructure analysis using an X-ray diffractometer showed that aging time reduced the annealing temperature to crystallize the YIG thin films. The crystallite size increased with the aging and annealing time. The average particle size measured using a field emission scanning microscope is in the range of 19.62 to 49.12 nm. The thickness of the films were between 49.13 to 72.63 nm. The results from a vibrating sample magnetometer used to measure the magnetic properties showed that the magnetization saturation of the films increased with the increment of solution aging time.Keywords: Thin film, Yttrium Iron Garnet (YIG), sol-gel, aging. IntroductionYttrium Iron Garnet (YIG) is a well-known ferrite material that is widely used for microwave devices, magneto-optical devices and optical communication [3] have reported on the influence of pH value on the structure and magnetic properties of YIG thin films. They found that higher pH value produces film with bigger particle size and higher saturation magnetization. N.B Ibrahim et al. [8] have reported that the longest aging solution produces Zinc Oxide (ZnO) film with the best crystalline and optical properties. The film is also thick and has larger particle size. Ebru [9] has also reported that the aging solution of lead zirconate titanate, Pb(Zr x Ti 1-x )O 3 (PZT) can change the preferred orientation and decrease the electrical properties of the films. S.M Rozati [10] reported the aged solution affects the structure, morphology and optical properties of fluorine-doped ZnO film. The intensity of crystallinity peak and optical transmittance increases with the increasing aging time. For the particle size, it decreases with the increasing aging day solution. However, there is no report so far about the effect of solution aging on YIG thin film prepared by a sol-gel method. In this study, the effect of annealing temperature and aging time on the structural and magnetic properties of YIG thin films by a sol-gel method is reported. The YIG solution was aged for 0 (fresh), 2, 7 and 11 days with different annealing temperature, 700℃, 800℃ and 900℃. Experimental MethodYttrium Iron Garnet (YIG) thin films on quartz substrate were prepared using a sol-gel method followed by a spin coating technique.

“…Nonetheless, the prospective applications of iron garnets require these materials to have superior magnetic and magneto-optical properties. As reported, the magnetic and magneto-optical properties of YIG are affected by the type and quantity of the substituted material, synthesis method and the microstructure of YIG particles [9][10][11][12][13]. Many studies have shown that the magneto-optical effects in iron garnets increase with the amount of substitution by * E-mail: yariciismail@gmail.com the elements such as Ce, La or Bi [14].…”

Cerium substituted yttrium iron garnet (Ce 0.2 Y 2.8 Fe 5 O 12 ; Ce-YIG) nanoparticles were produced via the sol-gel method from solutions of Ce-, Y-and Fe-based precursors, a solvent and a chelating agent. The solutions were dried at 200°C and heat treated at temperatures between 800°C and 1400°C for 3 h in air. The effects of pH and annealing temperature on the structure, phase formation, magnetic properties and crystallite size were investigated. A cubic YIG phase was obtained for the sample annealed at 1400°C. The presented results showed that the pH value of the starting solution affects the crystal size and consequently, the saturation magnetization.
