摘要：

A new current transformer is described by means of new results concerning the domain wall excitation in orthoferrites. The measured parameter is the geometrical position of the boundary between domains with opposite magnetizations. In a wide frequency band, including DC currents, the measurement results are a linear function of the measured current due to the very high domain wall velocity. They are not affected by temperature changes and mechanical factors. (C) 2000 Elsevier Science B.V. All rights reserved.
