Abstract

This paper studies the feasibility of integrated devices on nanoporous anodic alumina substrates filled with ferromagnetic nanowires. The presence of ferromagnetic material is responsible for an increase of the permeability at low frequency, and a tunability in frequency when an external DC magnetic field is applied. Tunability performance of the inductance and quality factor predicted by simulations are successfully validated by experiment. Below the FMR frequency, the measured quality factor is superior to that obtained for a similar device built on non magnetic Si wafer.
