摘要：

Using arrays of bistable magnetic nanowires, we show that their microwave absorption properties can be reversibly configured using low magnetic field cycling by virtue of the double ferromagnetic resonance absorption spectra. These characteristics lead to a single bifunction microwave filter that can be configured to work as a bandstop or a bandpass filter, making these materials very attractive for compact multifunction planar microwave devices. The bifunction microwave properties of these systems are successfully predicted using a mean field model for their magnetic configuration-dependent effective permeability.
