Abstract

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. [ABSTRACT FROM AUTHOR]

Abstract

The evolution of hysteresis and magnetoresistive properties of exchange-coupled Fe20Ni80/Tb–Co bilayers with modified interface was investigated in the temperature range from 79 to 450 K. Exchange bias field was shown to decrease monotonously with increasing temperature, demonstrating a very similar behavior for unmodified films and samples with ultrathin Ti spacer or selectively annealed permalloy layer. The observed dependence, therefore, is mostly attributed to the changes of the Tb–Co layer’s magnetization and magnetic anisotropy. Anisotropic magnetoresistance (AMR) value measured on all samples shown typical for the permalloy alloy reduction at higher temperatures regardless of the sample’s type. A simultaneous decrease of the exchange bias field and the value of the AMR effect was shown to open the possibility for the compensation of the temperature dependence of the medium’s response to the application of the external magnetic field.
