Synthesis and investigation of functional layers for composite multiferroics

This article is devoted to the synthesis and investigation of thin ferroelectric and magnetostrictive layers as potential constituents of composite multiferroics. We chose alloy Fe10Ni90 as magnetostrictive medium. The magnetic anisotropy and magnetoelastic properties of films Fe10Ni90 are investigated. It is shown that they can be significantly modified with a variation in the thickness of the samples in the range 40-80 nm. We chose polyvinylidene fluoride(PVDF) as ferroelectric medium. Its films were obtained by spin-coating and had a thickness of ∼200 nm. The analysis of the crystallinity and phase composition of the films are completed. It is established that the factors influencing on these properties are the thickness of the films and the conditions for their heat treatment. The magnetic properties of the PVDF / Fe10Ni90 film structures with optimized parameters of layered components are determinate.This article is devoted to the synthesis and investigation of thin ferroelectric and magnetostrictive layers as potential constituents of composite multiferroics.
