Magnetoelectric Properties of Nd_xBi_1-xFeO₃ Thin Films

Abstract:

Multiferroics based on BiFeO₃with spatially-modulated antiferromagnetic structure are investigated. The goal of this work is to define possibility of orientation phase transitions in magnetic and electric system by replacing Bi with 4f Nd ion depending on temperature in external magnetic field. On Nd_xBi_1-xFeO₃ films the measurements of permittivity, loss tangent at frequences 100 Hz < ω < 10⁵ Hz and at temperatures 300 К < T < 1000 K without magnetic field and in magnetic field with H=0.8 Т were made. A drop in temperature dependence of permittivity in magnetic field was found. Magnetoelectric properties can be explained in model of changing of magnetic structure in magnetic field as a result of interaction of electric and magnetic subsystems.
