金属有机分解外延是一种经济的湿化学方法，适合合成用于谐振器和振荡器应用的高质量低自旋阻尼薄膜。这项工作报告了铁磁共振的温度依赖性以及与单晶值一致的钇铁石榴石纳米膜的相关结构和磁性量。尽管湿化学沉积和旋涂存在缺陷，但在室温和 40 GHz 下，面外和面内谐振的品质因数分别接近 600 和 1000。这些值随着温度的升高而增加，并且比基于互补金属氧化物半导体压控振荡器的商业器件以相当的生产成本提供的值大 100 倍。
Metal-organic decomposition epitaxy is an economical wet-chemical approach suitable to synthesize high-quality low-spin-damping films for resonator and oscillator applications. This work reports the temperature dependence of ferromagnetic resonances and associated structural and magnetic quantities of yttrium iron garnet nanofilms that coincide with single-crystal values. Despite imperfections originating from wet-chemical deposition and spin coating, the quality factor for out-of-plane and in-plane resonances approaches 600 and 1000, respectively, at room temperature and 40 GHz. These values increase with temperature and are 100 times larger than those offered by commercial devices based on complementary metal-oxide semiconductor voltage-controlled oscillators at comparable production costs.
