TL;DR
This paper presents a theoretical analysis of stress-impedance effects in low magnetostrictive films, highlighting how external and intrinsic parameters influence the phenomenon.
Contribution
It introduces a model based on the Landau-Lifshitz-Gilbert equation to analyze stress-impedance effects considering various parameters.
Findings
Stress-impedance effects are highly dependent on external bias field and frequency.
Intrinsic factors like anisotropy orientation and damping significantly influence the effects.
Theoretical results align with expected physical behaviors of magnetostrictive films.
Abstract
A theoretical study of stress-impedance effect based on the solution of Landau-Lifsitz-Gilbert equation has been carried out. The results show that stress impedance effects depend largely on several extrinsic (external bias field, external frequency) and intrinsic (orientation and magnitude of uniaxial anisotropy, damping) parameters.
