Improving the sensitivity of asymmetric magnetoimpedance in exchange biased NiFe/IrMn multilayers [PDF]
, 2015 We investigate the asymmetric magnetoimpedance effect in exchange biased NiFe/IrMn multilayers and explore the possibility of tailoring the linear region of the curves around zero magnetic field by playing with the thickness of the ferromagnetic layers ...

Wide frequency range magnetoimpedance in tri-layered thin NiFe/Ag/NiFe films: experiment and numerical calculation [PDF]
, 2011 Given that the magnetoinductive effect (MI), skin effect and ferromagnetic resonance influence magnetic permeability behavior at different frequency ranges, the description of the magnetoimpedance effect over a wide range of frequency becomes a difficult
