摘要：

An asymmetrical and sensitive magneto-impedance effect was realized in twisted FeCoSiB and CoSiB amorphous wires magnetized with a dc-biased ac current, in which the impedance up to about 120 % / Oe. The asymmetrical magneto-impedance (AMI) is useful to construct linear field sensors without any de bias field. Mechanisms of the AMI are also discussed.
