Abstract

Magnetic hysteresis loop changes from two-phase to single-phase with decreasing Si interlayer thickness in Co/Si/Co/GaAs. Coercive field of 50 nm Co deposited on Si layer decreases with the increase of Si interlayer thickness. Deposition of Au layer between Co and Si changes the magnetic hysteresis loop. We propose that the formation of cobalt silicides at the interface of Co and Si modulate magnetic properties of the trilayer without Au buffer layer.
