Abstract
In this work, a new type of asymmetrical magnetoimpedance (AMI) effect has been found in a new type of NiFe/SiO2/Cu composite wire without applying any dc-biased magnetic field, in which NiFe/SiO2/Cu composite wires were fabricated by sputtering a NiFe seed layer on the SiO 2 layer and then electroplating another NiFe layer on the NiFe seed layer. A magnetization rotation model based on the coupling effect with bias field in the seed layer and the pinning effect by defects in the wire has been used to qualitatively explain the AMI profiles observed. © 2010 The Royal Swedish Academy of Sciences.
