Special Issue Information

Dear Colleagues,

Materials with coexisting multiple orders, named multiferroics, are attracting a great deal of attention and are part of the concept of multifunctional devices. On a fundamental level, multiferroic systems allow investigating the connection and interplay between symmetry, electronic correlation, magnetism, polarization, and/or elasticity. The coupling strength between the order parameters, as well as the underlying coupling mechanisms are crucial for the material physical properties, and govern the dynamical response to external driving fields.

This Special Issue of Symmetry features articles on multiferroic systems with an emphasis on symmetry, topology and dynamics. Contributions will cover a broad range of topics including:  Novel coupling mechanisms of ferroelectricity with magnetism in single phase and heterostructure materials, emergent multiferroicity  at interfaces,  topological states, such as skyrmions, ultrafast dynamics in composite multiferroics driven by electric and magnetic fields, as well as by elastic deformations, thermal excitations and multiferroics dynamics in temperature gradients, multiferroic photonics and electromagnetic wave propagation in ferroelectric/ferromagnetic heterostructures.  This Special Issue will include overview articles as well as progress reports on recent research developments and emergent applications.

Abstract
The paper presents the technology of ferroelectric-ferromagnetic ceramic composites obtained from PLZT powder (the chemical formula Pb0.98La0.02(Zr0.90Ti0.10)0.995O3) and ferrite powder (Ni0.64Zn0.36Fe2O4), as well [...] Read more.
The paper presents the technology of ferroelectric-ferromagnetic ceramic composites obtained from PLZT powder (the chemical formula Pb0.98La0.02(Zr0.90Ti0.10)0.995O3) and ferrite powder (Ni0.64Zn0.36Fe2O4), as well as the results of X-ray powder-diffraction data (XRD) measurement, microstructure, dielectric, ferroelectric, and magnetic properties of the composite samples. The ferroelectric-ferromagnetic composite (P-F) was obtained by mixing and the synthesis of 90% of PLZT and 10% of ferrite powders. The XRD test of the P-F composite shows a two-phase structure derived from the PLZT component (strong peaks) and the ferrite component (weak peaks). The symmetry of PLZT was identified as a rhombohedral ferroelectric phase, while the ferrite was identified as a spinel structure. Scanning electron microscope (SEM) microstructure analysis of the P-F ceramic composites showed that fine grains of the PLZT component surrounded large ferrite grains. At room temperature P-F composites exhibit both ferroelectric and ferromagnetic properties. The P-F composite samples have lower values of the maximum dielectric permittivity at the Curie temperature and a higher dielectric loss compared to the PLZT ceramics, however, the exhibit overall good multiferroic properties.
