Fundamental Database of Rare earths and Sm-Co Compounds

Due to their peculiar physical and chemical properties, the rare-earth elements and compounds have very wide applications, including industrial fields such as aeronautics and astronautics, energy resources, electronics, automobiles, architectures, petrochemical engineering and so on. In the past decade, based on the systematic experiments and repeated experiments, by processes of data accumulation, comparison and evaluation, we have developed the rare-earths database of crystal structures and properties, where for the first time the nanoscale effect on the data was introduced. Further, the database of the Sm-Co compounds has been developed. Both the databases have conventional polycrystalline and nanocrystalline systems for the data search, and the later contains data systems at the room temperature and with the varying temperature. Data of crystal structure, physical properties, magnetic features, mechanical properties, thermodynamic properties, phase stability and phase transformation characteristics, are contained in the database. The database provides the fundamental data for the rare-earth materials, and facilitates the design and development of new type rare-earth materials by serving as the references and quantitative guide. The database relates to 17 rare earth elements, and 9 rare earth compounds, including Crystal structure, physical properties, mechanical properties, magnetic properties, thermodynamic properties and phase stability, phase-change characteristics of 7 major categories of data.
