TLDR
In this article, magnetoimpedance (MI) studies were carried out, it was observed that the MI values were increased from 2.8% to 120% and the MImax value shifted to lower frequency when thickness of the NiFe film increased.Abstract:
NiFe films electrodeposited on Indium Tin Oxide (ITO) film coated on glass substrate. The NiFe films were electrodeposited at a current density of 19 mA/cm2. magnetoimpedance (MI) studies were carried out, it was observed that the MI values were increased from 2.8% to 120% and the MImax value shifted to lower frequency when thickness of the NiFe film increased. It clearly shows that thickness and conductivity of the substrate plays a significant role on MI values.A numerical-simulation conducted by Matlab, indicating the importance of the damping factor(α).read more

Sensitive field‐ and frequency‐dependent impedance spectra of amorphous FeCoSiB wire and ribbon (invited)
R. S. Beach,A. E. Berkowitz +1 more
TL;DR: In this article, a commercial impedance analyzer was used to obtain the spectra of amorphous FeCoSiB wires and ribbons at room temperature, and the phase shift due to the test leads was carefully measured and subtracted from the raw data to resolve the Spectra into resistive R(f) and reactive X(f ) components.

TL;DR: In this paper, the authors present a study of the effective magnetization Meff and the effective damping parameter αeff by means of ferromagnetic resonance spectroscopy on the NiFe materials Ni81Fe19 (NiFe) and Co40Fe40B20 (CoFeB) in FM/Pt, FM/NM, and FM/NiFe/Pte systems with the non-magnetic (NM) materials Ru, Cr, Al, and MgO.

Domain Observations on Iron Whiskers
R. W. DeBlois,C. D. Graham +1 more
TL;DR: In this paper, the authors have confirmed the appearance in iron whiskers of domain walls which violate the restriction that the normal component of magnetization must remain constant across the wall, and they concluded that the serrated wall contains an inner structure which largely eliminates any free poles.

The theoretical limits of giant magneto-impedance
TL;DR: An electrodynamic theory of GMI-effect in planar film conductors with uniaxial in-plane anisotropy is reported in this paper, where exchange interactions and two types of magnetic relaxation are considered.
