Influence of growth atmosphere on solubility limit of Ce3+ ions in Ce-substituted fibrous yttrium iron garnet single crystals

Magnetic properties of Ce,Gd-substituted yttrium iron garnet ferrite powders fabricated using a sol–gel method

“…The saturation magnetization of Y 2.9 Ce 0.1 Fe 5 O 12 is 28.0 emu/g. Saturation magnetization of the sample increase 2.0 emu/g than that of the pure YIG (satura- tion magnetization of pure YIG is 26.0 emu/g (Sekigima et al, 2001)). In a YIG system, non-magnetic Y 3+ ions occupy dodecahedral (c-) sites and magnetic Fe 3+ ions occupy octahedral (a-) and tetrahedral (d-) sites.…”

Preparation and properties of yttrium iron garnet microcrystal in P2O5–MgO glass

“…However, special attention has to be paid to precise control of growth conditions such as stability of growing temperature, atmosphere, as well as the pulling rate in the former growth technique [6]. Pure, defect free and congruent single crystals are not easily achieved.…”

Fabrication and magnetic properties of Ce1Y2Fe5O12 thin films on GGG and SiO2/Si substrates

“…3 that even the film annealed at 600 1C shows amorphous behavior, while the film of SiO 2 -700 exhibits the best crystallinity among polycrystalline Ce 1 Y 2 Fe 5 O 12 in our experiment. As for the SiO 2 -700 film, there are two weak and wide peaks representing Fe 2 O 3 (1 0 4) and YFeO 3 (0 4 0) besides Ce 1 Y 2 Fe 5 O 12 phase, which is considered to be a result of the narrow range of single YIG phase as can be seen from the pseudo-binary phase diagram of Fe 2 O 3 and Y 2 O 3 [12]. Compared to SiO 2 -700, the Ce:YIG (4 0 0) peak in SiO 2 -800 broadens towards low 2y values, indicating the presence of CeO 2 .…”
