Abstract
This paper reports the surface roughness effect on magnetic properties of Co thin films and the switching properties
of the multilayer structures. Surface roughness is varied by using Ni80Fe20 thin film as an underlayer. The surface
roughness of Ni80Fe20 thin films was controlled by applying different radio frequency (RF) biases to the substrate
during the sputtering of Ni80Fe20 underlayer. Surface roughness effect on the magnetic properties of Co thin films and
the switching properties of the multilayer structures were studied with Si/Ni80Fe20/Al/Co/Al and Si/Ni80Fe20/Al/Co/
