Magnetron Sputtering of CoFe and Permalloy

You are watching the sputtering of CoFe and Permalloy on a 3 inch Si wafer. The first faint plasma is the CoFe sputtering. When the CoFe gun shuts off the screen goes dark and the Permalloy gun is turned on. The plasma from the Permalloy deposition follows the path of the magnetic field.
