Inductive permalloy film

Silva, T.J., C.S. Lee, T.M. Crawford, and C.T. Rogers. 1999. Inductive measurement of ultrafast magnetization dynamics in thin-film permalloy. Journal of Applied Physics 85(11) 7849-7862. 

The structure of thin-film inductive recording heads results in the exposure to the environment of small areas of metal, often permalloy (Ni-20Fe), which is a relatively corrosion-resistant alloy. In fact, in-service corrosion of permalloy is not a problem and thin-film inductive heads have no history of corrosion-induced field failure. However, corrosion of permalloy can occur during manufacturing, leading to yield losses.
