Effect of Annealing on Extraordinary Hall Effects in Sputtered Granular Cu80Co20 Thin Films

摘要

The Extraordinary Hall Effect (EHE) has enhanced field sensitivity and is useful in sensor applications, a property often overlooked. There have been limited studies on EHE in granular as-deposited Cu-Co thin films. This work focuses on the EHE properties of annealed Cu-Co films by examining the magneto-transport in a series of thin films with vol.20% Co annealed at various temperatures.
