Modeling of asymmetric giant magnetoimpedance in amorphous ribbons with a surface crystalline layer
, 2005 A model describing the asymmetric giant magnetoimpedance (GMI) in field-annealed amorphous ribbons is proposed. It is assumed that the ribbon consists of an inner amorphous core and surface hard magnetic crystalline layers.

Asymmetrical giant magnetoimpedance in exchange-biased NiFe
Applied Physics Letters, 2010 Linear asymmetrical magnetoimpedance (MI) has been obtained in thin multilayer strips of exchange-coupled FeNi(5 nm)/IrMn(15 nm)/FeNi(40 nm)/Cu(100 nm)/FeNi(40 nm)/IrMn(15 nm)/FeNi(5 nm), in which the MI response is enhanced by including a Cu layer between the two 40 nm NiFe layers.

Giant magnetoimpedance effect at GHz frequencies in amorphous microwires
AIP Advances, 2019 Studies of magnetic properties and GMI effect of amorphous Co-Fe rich microwires reveal that they present GMI effect at GHz frequencies. Magnetic field dependences of GMI effect are affected by the post-processing conditions.
