Static and dynamic magnetization investigation in permalloy electrodeposited onto high resistive N-type silicon substrates

The present study reports on the development of permalloy thin films obtained by electrodeposition onto low-doped n-type silicon substrates. While changing from non-percolated clusters into percolated thin films upon increasing the electrodeposition time, the static and dynamic magnetic properties o...
