Special Issue Information

Dear Colleagues,

“Single-Crystalline Composite Materials (Second Edition)” continues the work of the previous Special Issue of Crystals, reporting the novelties involved in producing and applying various single-crystalline composites and new testing methods. This forthcoming second edition of this Special Issue will focus on recent innovative and pioneering works on single-crystalline composite materials and their production and examination, as well as the development of crystallization and research methods.

Single-crystalline composite materials are widely used in the modern aerospace, automotive, energy, and electronic industries. Despite the often-higher costs of obtaining products made of them, they are characterized by unique properties, distinguishing them from other materials. The properties of single-crystalline composite materials depend largely on the type and concentration of defects created in the final product. The defect structures—formed during crystallization and after potential subsequent material processing, e.g., heat treatment—can be influenced by many factors: the production technology used, the geometry of the final product, the types and amounts of dopants, etc.

The above issues, combined with the need to produce single-crystalline composites with new, different, and better properties, make it necessary to study the defect structures used for the development of existing crystal properties and creation of new ones, as well as for the modification of the parameters of their production. The results presented in the second edition of this Special Issue and the previously published first edition should represent an interesting collection of papers on different aspects of the production, processing, and properties of single-crystalline composite materials.

The exchange bias (EB) effect denotes a magnetic bias phenomenon originating from the interfacial exchange coupling at the ferromagnetic/antiferromagnetic materials, which plays an indispensable role in the functionality of various devices, such as magnetic random-access memory (MRAM) and sensors. Voltage control of exchange bias offers a promising pathway to significantly reduce device power consumption, effectively fostering the evolution of low-energy spintronic devices. The “magneto-ionic” mechanism, characterized by its operational efficiency, low energy consumption, reversibility, and non-volatility, provides innovative approaches for voltage control of exchange bias and has led to a series of significant advancements. This review systematically synthesizes the research progress on voltage control of exchange bias based on the magneto-ionic mechanism from the perspectives of ionic species, material systems, underlying mechanisms, and performance parameters. Furthermore, it undertakes a comparative evaluation of the voltage-controlled exchange bias by different ions, ultimately providing a forward-looking perspective on the future trajectory of this research domain.
