Tuning morphology and magnetic properties of sputtered permalloy by organic underlayers
We report the effect of polarity of self-assembled monolayers on magnetic properties and morphology of a deposited magnetic material. Sputtering of permalloy ( Ni 79 Fe 21 ) on a patterned structure of self-assembled monolayers (SAMs), with − C O O H and − C H 3 terminal groups, results in the forma...

gations reveal that the cluster formation gives rise to superparamagnetism, while the film
shows usual ferromagnetic behavior. The observed contrast in morphology and magnetism of permalloy is attributed to different growth mechanisms arising from the difference in reactive
nature of the terminal functional groups of the SAMs. |
