Peculiarities of Hysteretic Properties and Magnetostriction of Nano-Structured Fe10Ni90 Films

Abstract—The study is related to the investigation of hysteretic and magnetostrictive properties of single-layer Fe10Ni90 films and nano-structured [Fe10Ni90/Cu]p/Fe10Ni90 films, in which magnetostrictive layers are separated with a nonmagnetic interlayer. The magnetostriction effect is shown to depend on the total layer thickness; in this case, the magnetostriction of the [Fe10Ni90/Cu]p/Fe10Ni90 film structures was found to be higher than that of the single-layer Fe10Ni90 films. The observed peculiarity is associated with weakening the fixing effect of a substrate.
