We quantify the sensitivity by calculating the ratio jDZj=jDHj at low magnetic fields as a function of the frequency for samples cut with different orientations and show that considerable values in the linear region around zero field can be reached. The results extend the possibilities for application of exchange biased magnetoimpedance multilayers as probe element for the development and improvement of auto-biased linear magnetic field sensorMagnetoimpedância assimétrica de NiFe/IrMnAsymmetric magnetoimpedance of NiFe/IrMnarticle
