Special Issue Information
Dear Colleagues,
This Special Issue is mainly focused on coupling between magnetic and electric subsystems ordering. Ferroic materials attract much attention due to application demands. Many classical perovskites, ABO3, exhibit either ferroelectric or ferromagnetic properties. Double perovskites, AB’B”O6, also provide either magnetic ordering or electric ordering features. However, there is a lack of one-phase multiferroics; hence, the design and modelling of ceramic and crystal composites is an open field.
From an application point of view, the determination of several coefficients, e.g., spontaneous polarization, spontaneous magnetization, piezoelectric, electrostriction, magnetostriction, magneto-dielectric coupling, is necessary. Couplings to ferroelastic subsystems are yet to be appreciated. Phase transitions between ordered and nonordered phases also belong to the proposed topic of this Issue.
The stability of the studied materials’ ferroic features under strong electric and magnetic fields and under high pressure, as well as the effects of ageing, leakage currents, and temperature range of effective magneto–dielectric features will be verified.
Moreover, doping with suitable ions might additionally modify or induce demanded effects. Purposeful doping and those from technological processing are matter of interest. The studies of such structural features can be conducted using X-ray diffraction, electron microscopy tests, dielectric spectroscopy, optical spectroscopy, etc.
Finally, the determination of specific features of the double perovskites and their composites, with interesting new functionalities to provide prospects for applications is another encouraged topic. Authors are invited to submit research articles relevant to the topic addressed by this Special Issue.
