摘要：

The temperature dependence of the magneto-impedance effect in CoFeSiB amorphous wires is investigated in the temperature range between the room and Curie temperatures. A maximum value of 0.65 was found for the reduced impedance change ratio, its frequency dependence displaying two peaks, that reflect the changes of the magnetization dynamics in the circumferential direction as the frequency increases.
