Tunable microwave absorption of switchable complexes operating near room temperature.

ABSTRACT: Materials that are able to switch microwave radiation are strongly desired for their potential applications in electronic devices. In this paper, we show the spin-dependant interaction of spin-crossover materials with microwave radiation, namely, the ability of coordination compounds [Fe(NH₂trz)₃]Br₂ and [Fe(NH₂trz)₃](NO₃)₂ that undergo a cooperative spin transition between low-spin and high-spin states to operate as thermoswitchable microwave absorbers. The characteristics of the microwave reflection and transmission of these spin-crossover complexes were investigated at variable temperatures. The evolution of both the transmission and reflection spectra in the 26-37 GHz frequency band within the temperature rang
