Abstract
We show that at about 340 K a large (≅50%) change in the microwave absorption of a single crystal of La0.7Sr0.3MnO3 is caused by the application of a field of just a few tens of mT. This large magneto-impedance occurs at 10 GHz but is absent at 36 GHz, and we demonstrate that these results follow from the frequency and field dependence of the dynamic permeability of a ferromagnetic conductor.
