New Aspects of Understanding Magnetic Materials
Scope
High-performance permanent magnets and high-anisotropy magnetic materials are indispensable for realizing high efficiency in electric–mechanical energy conversion devices (motors and generators) and magnetic recordings. In terms of the materials science, material design of compounds having high-anisotropy and high-Curie-temperature is one important issue. Real materials are typical multi-phase, multi-component composite materials; their properties are determined not only by the intrinsic properties of the main phase but also by the interfaces between phases, microstructures etc., hence, multi-scale characterization and theories from an atomic scale to a microscale are required in order to fully understand the macroscopic magnetic behavior. Recent advancement in computational power and methods in electronic theory of magnetism and phase stability, new insights are emerging in understandings of magnetic materials including, in the realm of coercivity theory, magnetization reversal process at finite temperatures, and methodologies in bridging the atomistic and continuum micromagnetic theories, and in the realm of phase stability of novel materials, computation of formation energy for computational screening of candidate compounds for new permanent magnets, and computation-aided thermodynamic assessments. Another emerging area of science is the use of machine learning combined with computational techniques for predicting new compositions and new structures. This symposium will solicit invited talks on the recent important achievements in these fields.
