Manipulation of multi-degrees of freedom in ferroic-ordering

Ferroic-ordering is one of the essentials in applied physics and is studied in the ferromagnetics and ferroelectrics research fields. In these disciplines, new research fields such as spintronics, orbitronics, and energy-harvesting are arising. Ferroic-ordering can sustain energetically unstable conditions on long time scale, and can be manipulated by multi-degrees of the freedom in external and internal fields. The new manipulation scheme is being widely investigated and prominent ideas concerning manipulation are being reported every year. Thus, the number of manipulation methods of ferroic-ordering continues to increase. Furthermore, new ferroic-materials are reported every year. These ferroic-materials exhibit different behaviors at low dimensions. In such a remarkable development period, the growth of seeds directly linked to applied physics is anticipated. We believe each article will help in laying the foundation for new concepts in applied physics arising from future developments in ferroic-ordering.

This Selected Topics in Applied Physics (STAP) "Manipulation of multi-degrees of freedom in ferroic-ordering" contains 5 invited articles and 14 general articles that demonstrate the merging of the research fields of spintronics, ferroelectronics, dielectronics, and oxitronics. We hope that this project will provide readers with opportunities for collaborative research with new ideas.
