柔性磁性器件，即制作在柔性衬底上的磁性器件，由于具有可伸展、生物兼容、重量轻、便携和低成本等特点，在检测任意表面的磁场、非接触式致动器和微波器件等方面具有极大的吸引力。柔性磁性薄膜是实现柔性磁性器件各种功能所必需的。为了全面了解柔性磁性薄膜及其相关器件，综述了柔性磁性薄膜的制备方法、磁性和输运特性以及在磁性传感器、执行器和微波器件中的应用等方面的研究进展。介绍了制备柔性磁性薄膜的三种典型方法。拉伸或弯曲柔性磁性薄膜提供了一种对磁性薄膜施加机械应变的好方法，从而可以有效地控制磁各向异性、交换偏置、矫顽力和磁阻。最后，给出了一系列的例子，展示了柔性磁性薄膜在未来应用的巨大潜力。
Flexible magnetic devices, i.e., magnetic devices fabricated on flexible substrates, are very attractive in application of detecting magnetic field in arbitrary surface, non-contact actuators, and microwave devices due to the stretchable, biocompatible, light-weight, portable, and low cost properties. Flexible magnetic films are essential for the realization of various functionalities of flexible magnetic devices. To give a comprehensive understanding for flexible magnetic films and related devices, we have reviewed recent advances in the studies of flexible magnetic films including fabrication methods, magnetic and transport properties of flexible magnetic films, and their applications in magnetic sensors, actuators, and microwave devices. Three typical methods were introduced to prepare the flexible magnetic films. Stretching or bending the flexible magnetic films offers a good way to apply mechanical strain on magnetic films, so that magnetic anisotropy, exchanged bias, coercivity, and magnetoresistance can be effectively manipulated. Finally, a series of examples were shown to demonstrate the great potential of flexible magnetic films for future applications.
