FMR Measurements of YIG (Y3Fe5O12)Thin Films
摘要
鐵磁性氧化物釔鐵石榴石（Y3Fe5O12，簡稱YIG）為磁光效應與記憶元件中廣泛使用的材料，其薄膜型態之磁異向性為重要的研究課題之一。鐵磁共振（FMR）為分析鐵磁性薄膜或多層膜磁異向性的有效工具。本文詳述以鐵磁共振測量釔鐵石榴石薄膜，內容包括鐵磁共振系統介紹、樣品的準備與安裝、如何調制FMR訊號、如何旋轉樣品以造成樣品平面與外加磁場方向產生相對變化、以及實驗結果摘要等。

Ferromagnetic yttrium iron garnet (Y3FesOI2, YIG) is widely used in magneto-optical and memory devices. Magnetic anisotropy of YIG is an important research issue, especially in the form of YIG thin films. Ferromagnetic resonance (FMR) provides an effective way of analyzing the anisotropy properties of magnetic thin films and multilayers. This paper describes the detailed procedure of measuring YIG thin films by the ferromagnetic resonance (FMR) technique, The paper contains an introduction to the FMR system, sample preparation and installation procedures, how to tune the FMR signal, how to rotate sample to obtain the angular evolution between the sample surface and the applied field, and a brief summary of the experimental results.
