The Influence of Magnetoelectric Interactions on the Domain Walls in Multiferroics

The influence of magnetoelectric interactions on the magnetic structure, flexomagnetoelectric polarization and magnetization in thin multiferroics film has been investigated. The correlation between antiferromagnetic domain structure and ferroelectric domain pattern has been revealed. It has been shown the asymmetry of the antiferromagnetic vector distribution over multiferroics film in the case of 1090 and 710 ferroelectric domain walls. The direction of spins rotation in magnetic domain walls is determined by the type of ferroelectric domains and the antiferromagnetic vector in the centre of ferroelectric domain. The peculiarities of the micromagnetic distribution are reflected in the behavior of polarization and magnetization, which appears to be different for 1800, 1090 and 710 ferroelectric domains.

Changes in 70.53° magnetic domain structure on the surface of a perfect (11̄0) nickel crystal have been observed using white synchrotron X-radiation topography. The crystal was influenced by a variable [11̄0] magnetic field. At field strengths ≿ 100 A/m [111̄]-spike domains, thought to be traces of [011], 70.53° (oblique) magnetic domain walls, appeared within [111]-bands (0.4 mm wide) in the topographs. Reversal of the field produced similar spikes at equivalent field values but in different regions of the crystal.

Ferroelectric Domains

Ferroelectric domains are twins that are formed when PZT undergoes a phase transformation from a non-ferroelectric cubic phase to a ferroelectric tetragonal phase upon cooling below ∼375°C.,1 The tetragonal phase is spontaneously polarized in the direction of c-axis, making each twin a ferroelectric domain. Thin foils of polycrystalline Pb (Zr.52Ti.48)03 were made by ion milling and observed in the Philips EM301 with a double tilt stage.
