REIMEI Workshop: Physics of Advanced Functional Materials

Date: 10 - 11 October 2024

Place: 2nd floor ASRC Bldg, JAEA

Scope

The aim of this workshop is to share the latest results on magnetism, mechanical properties, and transport properties in bulk and thin films of functional materials. Researchers from Japan and abroad are invited to discuss physics arising from newly added degrees of freedom, such as the cross-correlation between magnetism and elastic waves, the generation of spin currents by nuclear spin, and magnetism and phonons in high-entropy alloys and amorphous systems. Phenomena that are expected to be applied to spintronics, such as paramagnons and spin waves in some aperiodic systems, will also be covered. In addition, the magnetic domain walls will be discussed, since the generation, annihilation, and control of magnetic domain walls are the most important key to the development of magnetic materials. The duality between the magnetic dipole and the electric polarization, which will be discussed in this workshop, is expected to develop into a new field of research. Since the properties of both thin films and bulk samples are directly related to device applications and functionality, detailed issues such as the effects of strain and distortion are also discussed.
