Studies of the correlations between physical properties and complex permeability of NiFe thin films
Source abstract
Abstract
We investigated the physical properties of Ni 81Fe 19 thin films intended for use in inductors operating at high frequencies. With a variety of characterization techniques, we measured saturation magnetization, anisotropy field, resistivity, and complex permeability of sputtered films with thicknesses in the range of 16–910 nm. We correlated the physical properties of the films with their complex permeability. Our analysis indicates that films under 100 nm have the characteristics most suitable for use in inductor structures. Such films would exhibit high permeability, allow inductors to operate at high frequencies and, at the same time, minimize eddy current losses.
