Progress and Prospect of Sm-Fe-N Magnets

open access: yesInorganics
High-performance but expensive neodymium-iron-boron (Nd-Fe-B) magnets are widely used in automotive and electrical applications. Prospective candidates for rare-earth-free magnets include Fe-based magnets such as L10-FeNi and α″-Fe16N2 phase.

Procedure for Sm-Nd Internal Isochron Dating Method on Basalt by Phase Separation

open access: yesYankuang ceshi, 2014
Accurately dating the age of basalt has been an important scientific issue for geologists. Due to its unique texture and composition, the basaltic minerals are limited to certain types, with scarce zircons in tiny grain sizes.

Correlation between rare earth elements in the chemical interactions of HT9 cladding

open access: yesNuclear Engineering and Technology, 2018
Metallic fuel has been considered for sodium-cooled fast reactors because it can maximize the uranium resources. It generates rare earth elements as fission products, where it is reported by aggravating the fuel–cladding chemical interaction at the ...
