摘要:

隨著信息技術的快速發展，應用于該領域的高頻軟磁材料成為目前人們研究的熱點。相比傳統塊體材料與微波鐵氧體材料，軟磁金屬薄膜有望在高頻條件下實現高磁導率,同時實現輕質化、薄型化等技術要求，具有廣闊的應用前景，因而受到磁性材料和微波器件研究學界的一致關注。面對微波集成應用技術向更高頻率發展的重大需求，提高材料的面內單軸各向異性是該領域研究的核心內容。本文分別針對感生各向異性、形狀各向異性、磁彈（應力）各向異性、交換各向異性、磁晶各向異性等不同類別，綜述軟磁金屬薄膜面內單軸磁各向異性與微波性能調控方面的進展。

Abstract:

With the rapid development of information technology, the high frequency soft magnetic materials have become one of the hot research areas. Compared with the traditional bulk materials and microwave ferrite materials, the soft magnetic thin films are expected to meet the technical requirements of high-performance, lighter and thinner at the same time, and show great potentials in applications. Therefore, they attract much attention from the area of magnetic materials and microwave devices. Facing the development of integrated microwave technology toward higher frequency, to improve the in-plane uniaxial magnetic anisotropy is the key in this field. As a review, this paper summarizes the developments of the tuning of in-plane uniaxial magnetic anisotropy and microwave magnetic properties in soft magnetic metallic thin films, starting from different kinds of anisotropies, including induced anisotropy, shape anisotropy, magnetoelastic anisotropy, exchange anisotropy, magnetocrystalline anisotropy, and so on.
