Electronic structure and x-ray magnetic dichroism in random substitutional alloys of f-electron elements [PDF]

, 1995
The Koringa-Kohn-Rostoker —coherent-potential-approximation method combines multiple-scattering theory and the coherent-potential approximation to calculate the electronic structure of random substitutional alloys of transition metals.

Critical Rare-Earth Elements Mismatch Global Wind-Power Ambitions

One Earth, 2020
Summary Wind power needs to be expanded rapidly across the world to stabilize our climate. However, there are increasing concerns about conflicts between the supply of rare-earth elements (REs) (mainly neodymium, praseodymium, and dysprosium) and the ...

Coexistence and competition of multiple charge-density-wave orders in rare-earth tri-telluride RTe3

, 2014
The occurrences of collective quantum states, such as superconductivity (SC) and charge- or spin-densitywaves (CDWs or SDWs), are among the most fascinating phenomena in solids. To date much effort has been made to explore the interplay between different
