2025年1月15日 · This correlation offers a pathway for a simplified, rapid assessment of YIG film quality, avoiding the need for complex time-consuming characterization techniques. In addition, we report a comprehensive investigation into the influence of pulsed-laser deposition parameters, including deposition temperature, pressure, laser fluence, frequency ...

Yttrium iron garnet (YIG) is a kind of synthetic garnet, with chemical composition Y 3 Fe 2 (FeO 4) 3, or Y 3 Fe 5 O 12. It is a ferrimagnetic material [1] with a Curie temperature of 560 K. [2] YIG may also be known as yttrium ferrite garnet, or as iron yttrium oxide or yttrium iron oxide, the latter two names usually associated with powdered ...

2023年1月16日 · Spinel-type ferrites were the first material utilized in microwave devices; however, yttrium iron garnet (YIG) has low dielectric losses and is exploited in many applications. Owing to its high Faraday rotation, YIG films are utilized in magneto-optical applications.

2019年4月1日 · In the current study, we report for the first time the total substitution of Tb3+ and Er 3+ ions into the YIG structure to obtain garnet ferrites that are suitable for a wide range of MO applications. We also investigate the crystallisation of YIG and TbErIG films under different annealing conditions (air, oxygen and argon atmospheres).

We report on the growth of thin films of yttrium iron garnet (YIG) on dielectric substrates. Such films have historically been challenging to grow due to either cracking or incomplete crystallization of the films. We have established the proper growth parameters by tuning seed layer thickness to an optimum of 45 nm.

2022年7月27日 · 钇铁石榴石 （英语：Yttrium iron garnet或YIG） 是一种合成石榴石, 化学成分为 Y 3 Fe 2 (FeO 4) 3 或Y 3 Fe 5 O 12。 它是一种亚铁磁性材料 [1] ，居里点为560 K， [2] YIG也可称为钇铁氧体石榴石，或称为铁氧化钇或氧化钇铁，后两种名称通常与粉末形式有关。

Yttrium Iron Garnet (YIG) is a ferrimagnetic oxide with nearly cubic symmetry, composed of trivalent metal ions, known for its low magnetic losses at microwave frequencies. It is widely used for studying spin waves, magneto-optical effects, and static magnetic properties, especially in …

YIG (chemical formula Y3Fe5O12, crystal structure depicted in Fig. 1) is a ferrimagnetic insulating oxide with the lowest magnon damping of any known material. Its exceptionally narrow magnetic resonance linewidth — orders of magnitude lower than the best polycrystalline metals — allows magnon propagation to be observed over centimetre distances.

2013年5月1日 · This work presents the study of the ferrimagnetic composite, constituted by Y3Fe5O12 (YIG) and Gd3Fe5O12 (GdIG) phases, through solid state synthetic route and submitted to high-energy mechanical...

This article uses spark plasma sintering (SPS) to synthesize high-entropy (HE) Y0.6Gd0.6Sm0.6Eu0.6Dy0.6Fe5O12 (HEG) and traditional garnet Y1.2Nd1.8Fe5O12 (YIG). Studied the effects of 2 MeV He2+ irradiation (1 × 1014 ions/cm2 - 1 × 1017 ions/cm2) on the crystal structure, mechanical properties, and chemical stability of ceramics.
