Special Issue Information
Dear Colleagues,
Switching magnetic polarization by electric signals and vice versa is currently a topic of intensive research regarding technologic application but also regarding a fundamental physics-related understanding of the magneto-electric-coupling mechanism. The aim here stems from memory applications via multijunction information processing and sensors to quantum mechanically coupled states for quantum information technology. In recent years, great progress has been achieved in fabrication technology, experimental characterization, and theoretical understandings of materials and heterostructures, utilizing various coupling mechanisms. In this context, generally speaking about magnetoelectric and multiferroic materials, magneto-electric coupling can be intrinsically in and also mediated via boundaries in heterostructures, utilizing, for example, magneto-strictive, piezoelectric, and ferroelectric/-magnetic materials. Nonetheless, an understanding of the fundamental processes is still not complete and research is devoted to uncovering the interplay of atomic order, orbital distribution, defects, and dopant states as well as interface properties with electric polarization and magnetic exchange processes. Extending the magneto-electric regime, readout or detection by means of light as a further step towards even more sophisticated device applications has recently gained research interest, as well.
This Special Issue aims at providing comprehensive insight into state-of-the-art as well as topical research within areas such as regarding the fabrication and experimental characterization of those systems, the theoretical understanding of the coupling mechanism at the atomic level, feasibility studies, and device demonstration. Additionally, aspects of the fundamental polarization and spin interaction processes in pure magnetic or ferroelectric materials when related to the coupling mechanism may be discussed. Topical reviews as well as original research is welcome.
