Silicon substrate integrated ferromagnetic nanowires for microwave applications

Abstract

Magneto-dielectric nano-composite (magnetic nanowire in anodic alumina) films are fabricated on silicon substrate. Kerr measurements reveal magnetic properties of the nano-composite, while the microwave measurements in the frequency band 0.2-18 GHz show relatively low dielectric losses. After a proper optimisation these nano-composite films may be used in nonreciprocal and magnetically tuned devices in silicon substrate based Multi-Chip Modules (MCM).
