摘要
Converse microwave measurements have been performed to measure magnetoelectric effects at room temperature on Sr3Co2Fe24O41 hexaferrite slabs. The measured properties include the magnetic permeability and strain as a function of the electric field E. In this paper, the microwave permeability changes are due to the application of a DC voltage affecting the static magnetization rather than shifts in ferromagnetic resonance. We conclude that when an electric field is turned on the ferrite exhibits broken symmetries for time reversal and parity.
