采用射频溅射法在柔性衬底上制备了用于宽带噪声滤波器的[FeNi-FeMn]N/[MnIr-FeCo]N混合多层膜。通过组合具有不同厚度的两种类型的多层膜，其中FeNi-FeMn被设计用于低频范围，MnIr-FeCo被设计用于高频范围，可以实现用于宽带噪声滤波器的混合薄膜。其从1.5到7 GHz的宽范围（反射损耗小于-10 dB的吸收宽度）使这种混合薄膜具有未来应用的前景。
Hybrid multilayers of [FeNi–FeMn]N/[MnIr–FeCo]N deposited onto flexible substrates oriented for wideband noise filters were fabricated using rf sputtering deposition. By combining the two types of multilayers with various thicknesses, where FeNi–FeMn is designed for the low frequency range and MnIr–FeCo for the high frequency range, one can realize a hybrid thin film for wideband noise filters. Its broad range from 1.5 to 7 GHz (the absorption width where the reflection loss is less than −10 dB) makes this hybrid thin film promising for future applications.
