Synthesis of Iron Yttrium Garnet Nanoparticles by Reverse Microemulsion Method
Colloidal nanodispersion of Iron Yttrium Garnet has been preparedbymixing the two ternary mixture of Triton X-100 (surfactant), n-heptane and aqueous solution that differing only in the aqueous phase.Ethanolwas added as cosurfactant and mixed them by ultrasound bath. By mixing these twomicroemulsions, Iron Yttrium garnet (Y3 Fe5 O12) nanodispersionwas obtained. Solids were settled by centrifuge...
متن کاملخواص ساختاری و مغناطیسی ذرات گارنت ایتریوم آهن با جانشانی یوروپیوم سنتز شده به روش سل- ژل
In this work, Europium ion (Eu3+) substituted yttrium iron garnet particles EuxY3-xFe5O12 (x=0.0, 1.0, 2.0) were synthesized by the sol-gel method. X-ray diffraction (XRD) patterns confirmed the pure garnet structure for all samples. The garnet phase was studied by using Far-FTIR and Raman spectroscopy. The results of vibrating sample magnetometer (VSM) represents that saturation magnetization ...

In this work, samarium ion (Sm3+) substituted yttrium iron garnet nanoparticles Y3-xSmxFe5O12 (x=0.0, 0.2, 0.3) were fabricated by the sol-gel method. X-ray diffraction (XRD) patterns confirmed the pure garnet structure for all samples. The garnet phase were studied, using, Far-FTIR. The results of vibrating sample magnetometer (VSM) represents that saturation magnetization decrease with increa...
متن کاملMagneto-Optical Faraday Effect of YIG Films with Random Multilayer Structures
Magneto-optical Faraday effect of Bi-substituted yttrium iron garnet (Bi:YIG) films with random multilayer structures was analyzed by using the random matrix approach. It was found that the random multilayer structure is very effective for enhancing the Faraday effect of the Bi:YIG film, which is much superior than that of the periodic multilayer films.

Praseodymium ion (Pr3+) substituted yttrium iron garnet nanoparticles PrxY3-xFe5O12 (x = 0.0, 0.1, 0.2, 0.3, 0.4) were fabricated by the sol-gel method. X-ray diffraction (XRD) patterns confirmed the pure garnet structure for all samples. The chemical bonds and the garnet phase were studied by using Far-FTIR. The magnetic hyperfine parameters were obtained by MÖssbauer spectroscopy and confirme...
