MOKE study of hybrid magnetic thin films: Permalloy on molecular self-assembled monolayer

► MOKE study of Permalloy-Py thin films deposited on self-assembled monolayer-SAM. ► Initial cluster like growth of Py on non-polar SAM gives paramagnetic response. ► Thick film of Py on non-polar SAM shows ferromagnetic behavior. ► Both thin and thick film of Py on polar SAM illustrated ferromagnetic behavior. ► Surface chemistry of SAM can tune-up the magnetic properties of ferromagnetic thin films.
