Microwave Absorption Performance

Exchange-coupled hard-soft magnets have been considered as promising microwave absorbers. However, it is difficult to make further breakthrough in microwave absorption performance due to the deficient dielectric loss. In this...

The magneto-structural correlation between μ2-phenoxido bridged iron(iii) complexes are studied by structural analyses, magnetic, HF-EPR measurements, and DFT calculations. The magnetic exchange coupling is governed by the Fe–O–Fe angle and the crossover point from AF to F interactions is θ at 97.83°.
